Our Story

For over 25 years, Nerdcore has been The trusted source for IT support Perth

​

Early History: IT Support Perth for Architects and Engineers

Nerdcore was founded in 2001. In the early years, most of our clients were architectural and engineering firms in Australia. In those days, it wasn’t easy to buy a CAD workstation. You couldn’t just go online, and custom configure a PC with a high-end graphics card and enough RAM to run leading edge CAD software. Nerdcore built a thriving business around providing specialized computer hardware sales, network configuration, and support. Our “Microstation” CAD workstations set the standard for performance and reliability.

​

Growing Expertise, Expanding Influence

As time went on, Nerdcore assembled an unrivaled pool of talent. Word spread about the technical insight and exemplary service provided by Nerdcore staff members. Before long we became the leading IT support Perth provider in the South for IT businesses Perth , retail, manufacturing, legal, financial services, health care, non-profit orgs, educational institutions and much more. As our consulting business grew, we eventually phased out of selling hardware and software.

​

We Transformed Our Approach to Better Serve YOU

Typically, IT support Perth providers subscribe to one of two philosophies: 1) managed services or 2) break fix.

 

Managed services providers offer pre-packaged IT support Perth plans that almost never deliver a perfect match to their clients’ needs. The managed services approach is clumsy and inefficient. It might appear to be a good deal at first glance but “predictable pricing” proves to be a false economy when necessary services are deemed “out-of-scope.”

Break-fix support providers literally wait for a disaster to happen before acting. Break fix is risky!

In 2008, while many other IT support Perth providers were still offering break-fix support, or were just beginning to adopt the managed services model, Nerdcore transformed IT support strategy.

We adopted a framework for support that is predictable and proactive while also being custom tailored to our clients’ needs. We employ flexible strategies that enable Nerdcore to complement internal IT departments Perth without competing with them.

Our customer-focused approach to delivering IT support Perth has proven to be wildly successful. It has resulted in tens of thousands of happy computer users at hundreds of businesses, and a decade (and going) of consistent double-digit year over year growth for Nerdcore Computer repairs perth

LaCie Data Recovery | File Data Recovery | Nerdcore computers service centre | 1300637326

LaCie Data Recovery

 

LaCie offers a broad selection of products, from personal hard drives to RAID arrays and NAS servers. Their NAS devices, in particular, have been very well received, and they’re very affordable options for small businesses and even home networks.
NAS and RAID devices from LaCie are very dependable, and have at least one type of redundancy built into their design (meaning that when one hard drive fails, data can be reconstructed). Nevertheless, failure of multiple hard drives and errors during RAID setup and maintenance can sometimes cause data loss. We have extensive experience with all LaCie products, and recovery chances on any LaCie product tend to be very high.

LaCie Server Data Recovery

When a LaCie server such as the LaCie 12big rack network fails, it’s prioritized and worked on by data recovery engineers with training and experience in server recovery. The data recovery process will differ for each device, as different recovery methods are necessary for different issues. First, engineers will determine whether remote data recovery is possible. Remote recovery is used when a server’s failure hasn’t impacted the integrity of data.
For instance, if a single drive has failed on a NAS or RAID device and corruption is preventing the device from recovering on its own, our engineers can use block level access to fix the issue and allow the device to be remounted normally. In some situations, hard drive data recovery is necessary, for instance if multiple hard drive failures have been detected. In these cases, our engineers work to develop an exact clone of the failed drives which can be used to rebuild the lost data. The entire process can usually be completed in a day or two, and a full recovery of the lost data is very likely.

LaCie Error Codes and Data Loss Symptoms

LaCie products indicate serious operating errors in several ways. The LaCie 12big rack network uses audible alarms and lights to alert users of any serious issues. If your device displays a constant drive light combined with a slow beeping sound (a beep about a half second long, recurring every eight seconds), one or more drives have failed or cannot be read by the LaCie 12big rack network. In some situations, data recovery will be necessary, particularly if the device cannot successfully start up.
If you suspect multiple hard drive failure, you should be very careful not to reinitialize the device without contacting LaCie support or a data recovery professional. Reinitialization can sometimes overwrite data if multiple drives have failed, making data recovery much more difficult.
Beeping sounds are also used by LaCie RAID devices and home drives to indicate drive failure, commonly either the slow beep mentioned above or several beeps of differing pitch combined with other symptoms (for instance, if the LaCie device won’t mount or the computer can’t recognize it). This is sometimes accompanies by a GUI error code, depending on the product.
GUI codes are usually very straightforward, and give a simple reason for the device’s issues, for instance, “hard drive failure detected.” Occasionally, only an error code will be displayed. These error codes usually indicate an inability to read or write data, or a problem with data perimeters.
For instance, Error Code -10 is used by some LaCie devices to indicate that the device cannot start.  Error code -50 indicates a file system issue.  As there are dozens of LaCie products, error codes vary; speak with one of our specialists by calling 1300637326  to diagnose your device’s failure.

LaCie Data Recovery Tips

It’s important to avoid taking any action that could compromise the integrity of data, especially with LaCie servers. At the first sign of data loss, immediately shut down the failing device and contact a data recovery engineer.
Our engineers will assess whether remote data recovery is possible, as this is the fastest option in most cases, and will advise you on the next steps, including an estimated cost and turnaround time.
If your LaCie storage product has failed and you need reliable service to get your data back, please contact us by phone or email for more information or set up a case online.

Western Digital Data Recovery | Nerdcore computers service centre | 1300637326

Western Digital Data Recovery | Nerdcore computers service centre | 1300637326
Western Digital While exceptionally good drives, Western Digital, like all other hard drives, occasionally fail. Sometimes these failures can be due to read/write head problems or service track corruption. Usually this damage occurs due to improper cooling, allowing the drive to reach temperatures above its maximum recommended operating temperature. Often when there are head or microcode issues, the drive will either make a clicking noise, or display the wrong drive size at POST. For instance, you might see “Western Digital 120 GB WDAC1200BB,” instead of “Western Digital Caviar 60 GBWDAC600BB.” This is a sign that the heads or microcode have failed, but it is still a completely recoverable condition in most circumstances. If the drive is clicking, it is important to turn it off immediately. This can damage the platter media over time. If you have a failing Western Digital hard drive, and would like more information about how we can help you, please call us at 1300 637 326

Please keep in mind that hard drives are delicate instruments. Like any other delicate instrument, if they are not handled with care or properly cooled, you may experience a failure. Hard drives are sensitive to heat, rapid temperature changes, static electricity, power surges and physical shock. We estimate that most hard drive failures occur due to operating conditions, not manufacture defects.

Nerdcore computers service centre, is a Western Digital Service and Support Platinum Partner for data recovery. We have been authorized by WDC to open and recover data from WD hard drives without affecting your warranty.

Seagate Data Recovery Services. Seagate data recovery services with a no data, no charge guarantee. Seagate Hard Drive Data Recovery Technology

Since the late 2001s, nerdcore computers service centre has performed recovery procedures on tens of thousands of Seagate desktop and laptop drives. Seagate introduced many modern innovations in data storage technology, and while their drives are reliable overall, our knowledge of some recurring issues allows for an easier data recovery process.

Early Seagate drives (including models introduced from the late 1990s to the mid-2000s) frequently encountered spindle issues – a problem that has been largely corrected in recent generations. Spindle seizures could suddenly prevent drives from operating, and our engineers perform full platter replacement procedures to recover data from these early models.

Call 1300 637 326  for a free evaluation.

Basic Seagate Hard Drive Failure Modes
The basic failure modes of a Seagate are listed below. We recommend contacting a qualified Seagate data recovery company if any of these issues are present:

Bad Heads – Seagate drives with bad heads will spin up and click several times, then power down. This issue is often caused by physical damage.The data recovery procedure will include replacing the heads in an ISO 5 clean room environment, turning off auto reallocation and media cache if applicable so that the drive can be cloned. We will often need to use firmware repair equipment to complete this type of recovery.

Service Track Damage – Seagate drives with service track damage will spin up and will likely sound healthy. The spindle operates properly and will continue to spin, but the drive may not be recognized by the system BIOS (or equivalent). If it is recognized, it may display an incorrect model number, serial number, or size attribute.Service track issues are fairly common in the Seagate drives that we receive. The data recovery process will vary depending on the drive family. For example, a Seagate 7200.11 service track issue would require an entirely different fix from a 7200.12.In our experience, 7200.11 drives generally had problems with the defect lists and the translator, while drives from the 7200.12 family can get hung up on sections of the microcode. These issues can usually be fixed by turning off auto reallocation and media cache with special equipment. In any case, we would perform a free evaluation to provide a quote before deciding on an appropriate data recovery technique.

 PCB Failure – Seagate drives with electronic/PCB issues may not spin (the spindle does not engage when the drive is connected to a power source). The data recovery process will often require the removal of damaged diodes. Our engineers may also need to swap the ROM to a new printed circuit board. This process requires extremely specialized equipment, including firmware repair tools, and should never be attempted outside of a data recovery laboratory.

Stuck Write Heads – The drive will not spin and will emit a repetitive low pitch buzzing noise. Ideally, this will be fixed by opening the drive in a cleanroom and moving the heads back to the landing zone/ramp. If the heads are damaged, they will need to be replaced with an adequate donor.

Seized Hard Drive Spindle – The hard drive will not spin and will emit a repetitive low-pitch buzzing noise. This is rare on newer Seagate drives. The data recovery process will include a full repair of the spindle or a complete platter swap to an adequate donor. This type of failure is normally caused by physical abuse/dropping.

Other issues may occur, and we highly recommend seeking a professional Seagate data recovery company if you notice any of the failure modes listed above. Never attempt to open a Seagate hard drive outside of a cleanroom, as this may permanently damage the drive.
Seagate Hard Drive Data Recovery Technology | Nerdcore Computers Service Centre | 1300637326

We offer data recovery services for all Seagate models including these popular lines:

    Barracuda Series
    Backup Plus External Hard Drives
    Enterprise Performance Hard Drives and Solid-State Drives
    Seagate Desktop SSHD and HDD
    Seagate Ultra Mobile HDD and Ultrathin HDD
    7200 Series and More

This is not a complete list, and we currently support all Seagate media.

Nerdcore computers service centre laboratories are equipped with advanced microcode repair tools, which allow our engineers to quickly recover data from most Seagate drives. In many instances, we also need to repair failed read/write heads and other components in a Class 5 clean room in order to get a full copy of all of the files on the disk. We offer high success rates for all Seagate models, and all of our laboratories are equipped to handle these cases.
Signs of Failure for Seagate Hard Drives

Seagate hard drives can present a wide number of failure symptoms, and some drives might display a few different symptoms simultaneously. To completely diagnose the damage, you need a professional data recovery evaluation.
Hard Drive PCB

Many Seagate data recovery cases require PCB repair.

The following symptoms can accompany physical failures:

    Clicking Noises
    Drive Doesn’t Spin
    Extensive File Corruption
    Hard Drive Displays Inaccurate Specifications (Free Space, Total Size, Etc.)
    Hard Drive is Excessively Hot to the Touch
    Computer Cannot Detect Drive

If you notice any signs of media issues, turn your computer off and refrain from operating your hard drive. Don’t run firmware utilities, data recovery software, or any other applications. Call 1300 637 326  to speak with a Seagate hard drive data recovery expert from Nerdcore computers service centre.

Our Process for SSD Data Recovery

SSD data recovery is very different from hard drive data recovery and requires completely different tools.  Whereas hard drives store information on magnetic materials that physically move, solid state drives don’t have  any moving parts.  They’re much faster than hard drives, but they’re also subject to memory wear and physical damage.  This means that while SSD is reliable, it’s not perfect, and engineers need to use a specialized process to recover corrupt or deleted files.

The basic process for SSD data recovery starts with an evaluation. We provide a free price quote, which ranges depending on several factors. The most important factor is whether the case is considered a Level 1 or Level 2 recovery:

    Level 1 Solid-State Drive Recovery – At this level, the SSD may require minimal physical repairs, but most repairs will involve the firmware of the drive (accessed using hardware developed within the nerdcore computers service centre research laboratory). We may also be able to access the SSD and fix corrupt files with software. We perform an image of the drive using the drive’s intact controller, but we do not remove the chips that store information (the flash chips).

    Level 2 Solid-State Drive Recovery – These are more severe recoveries with noticeable physical damage or electronic damage. We will need to remove the memory chips, create a raw dump of each individual chip, and then apply the wear-level algorithm, which the SSD uses to prevent premature memory wear (more information on wear leveling can be found on this Wikipedia page). We usually identify data structures to determine the wear-leveling algorithm; this is often a very difficult process, but our success rates are still high.

In either case, we will use special tools and software to read the information and to create a usable copy of any files on the device. It is important to note that most solid-state drives do not have user-serviceable components, and we strongly recommend sending any damaged SSD to a qualified data recovery center.

Intel 525 Series mSATA solid state driveCommon SSD failure symptoms include slow transfer rates, repeated file access issues, file corruption, and a large number of bad sectors. Solid-state drive issues are often progressive, which means that they become worse as the drive continues to operate. Because of this, we do not recommend running data recovery software on an SSD. You should shut your drive off if you encounter any of these issues or if you lose data due to file deletion or software error.

Our SSD data recovery services feature:
    Support for All Solid-State Drives – Nerdcore computers service centre offers services for both SATA and PCI Express-based solid state drives from Samsung, Crucial, Intel, Toshiba/OCZ, Kingston, and dozens of other manufacturers. We also offer services for traditional hard drives and hybrid HDD-SDD devices.

    Priority Options – Get your data back on your schedule. We provide options for every budget including an emergency service, available 24 hours a day, 365 days a year, and our team can help you choose an appropriate service level for your case.

    Superior Technology and Excellent Success Rates – We can efficiently repair physical, electronic, or logical damage, and our research and development team regularly introduces new technologies for various SSD devices. Nerdcore computers service centre offers the highest success rates available anywhere.

    Better Security Through Department of Defense Standards – By following the Department of Defense (DOD) regulations for information storage and access management, we protect your privacy at all times.

    Guaranteed Results – nerdcore computers service centre exclusive no data, no charge policy ensures that if your requested files aren’t recovered, you do not pay a service charge. Call our customer service team for more information.

Don’t trust your data to an inexperienced company.  Because SSD technology is manufacturer specific, you need a data recovery company that has experience with your exact device.

At nerdcore computers service centre offers the best solutions for SSD data recovery, and since 1997, we have maintained a full R&D department in order to treat every case effectively. Our teams understand the intricacies of SSD technology, and we’re ready to provide an accurate quote for your case through a free evaluation.

Why Choose us for your Hard Drive Data Recovery by Nerdcore computers service centre

Our biggest advantage for hard drive recovery is having a massive largest inventory of used hard drives on-site. Because we do not have to buy parts drives on the open market like our competitors, we can afford to use more parts and try harder. This results in greater successes with physically crashed hard drives. We will attempt recoveries (many successful) that others deem unrecoverable.
Having almost free parts also allows us to keep our fees lower as we don’t have parts and shipping costs to pass on.
Turnaround time can be kept to a minimum as we don’t lose time waiting for parts drives to be shipped to us.  This also allows us to perform emergency after hour recoveries while our competitors must source and order hard drive parts.

How Much Does Computer Repair Cost? Nerdcore computers service centre computer repairs prices. Cost effective when and were you need us.

How Much Does Computer Repair Cost?

 

The average price per hour for computer repairs ranges between $120 to $150. For example, a hard drive replacement could take two hours costing roughly $300.

Staring ahead at the computer screen, anxiously awaiting a web page to load, you finally admit maybe there’s a problem with the computer.

The computer is only six months old, so there’s no reason a web page should take 30 seconds to appear. Maybe there’s a problem with the software that’s causing delays.
Then you realize that Adobe update you clicked on a few weeks ago may not have been from Adobe.
Web-based malware is often the culprit for computers running slower than normal. Oftentimes users don’t realize malware is on their Mac or PC until they’re taken to websites they don’t recognize, their search engines change or their computers slow down.
Users can find and fix malware problems on their own, for free. But sometimes users prefer to call computer repair professionals to fix these and other problems.
“It’s really more of a personality question versus their skills,” says Nick Veloutsos, owner of Nerdcore computers Services in Hughesdale

What is malware?

Malware is any program installed on a computer that doesn’t belong. Most malware lands on computers when users click on legitimate-looking pop-up icons telling them to update their software, Nick says.
Often malware will make subtle changes to your system, including adding attachments to your web browser’s toolbar, or changing your homepage. While these may seem innocuous, the more malware your computer gathers, the slower it runs.
“The more of those little things you have, the slower your computer will get, and the greater the chances that things are going to go wrong,” Nick says.

Removing malware

Users can eliminate malware themselves if they’re confident enough to navigate a computer’s settings.
“It’s going through the program list and removing what doesn’t belong,” Nick says.
But Jones also has clients who aren’t comfortable altering their computer’s settings, largely out of fear of breaking something.
The cost of hiring a computer professional varies by provider. Jones charges $120 per hour, though sometimes during service calls he’s also able to answer questions and solve other tech-related problems for clients.

Hiring a computer repair professional

If you do hire a professional to check your computer’s software, it’s important for them to physically be on-site to check your system.
Service providers can use software to access your computer remotely, without ever setting foot in your home. But because there are multiple forms of malware it’s nearly impossible to provide a one-size-fits-all solution for a slow computer. Technicians should also physically check the computer to make sure there aren’t signs of larger problems, such as a fan that never stops running, Nick says.
That’s difficult to do without ever leaving the office.
“You’re basically fighting with one hand tied behind your back,” Nick says.

Computer hardware problems

Not all computer problems are software related. If your computer won’t turn on, chances are you have a hardware problem.
Hard drives are the most common and practical computer parts to replace. The equipment costs between $60 and $100, and the job takes about two hours. Jones says replacing a hard drive is roughly a $300 job.
Before paying for a hardware repair, consider the age of your computer. If you have a six-year-old computer that needs several hundred dollars in new parts it might be time to buy a new one.

Best Practices for Network Border Protection | Network Security Software | Protect your computers network with low price security software | Ring 1300nerdcore.com.au

When it comes to network traffic, it's important to establish a filtering process that identifies and blocks potential cyberattacks, such as worms spreading ransomware and intruders exploiting vulnerabilities, while permitting the flow of legitimate traffic. In this post, the latest in a series on best practices for network security, I explore best practices for network border protection at the Internet router and firewall.

Before we begin exploring best practices, it is important to note that these recommendations are geared toward large organizations and government agencies and would not likely be appropriate for a home network or very small business network. For example, in a small business or home network, the firewalls and routers might be collapsed into one device. This post will primarily focus on larger, enterprise networks where the Internet router and firewall are broken out into distinct devices, as shown in the figure below

It is also important to note that this post will primarily focus on filtering of inbound traffic. Filtering of outbound traffic is also very important for organizations and will be the subject of a future post.

Let Your Routers Route

The philosophy of many network administrators is let your routers route. In a larger network with specialized devices, you want to let the Internet router do its primary job, which is to pass traffic. Having said that, there are exceptions where traffic/security issues will require some basic blocking on the Internet router. Here are some principles to keep in mind:

    Don't add an access control list (ACL) entry for every suspicious IP address. I once worked for an organization that would add an ACL entry to the Internet router every time it saw an attempt from outside to do something suspicious, even if that attempt was blocked by the firewall.

    The problem with this approach is that it creates a massive ACL. The Internet router now has to process every entry in the ACL when filtering traffic. This approach also makes it hard for people who manage the ACL, because network administrators must determine why a particular entry was added to the ACL, and whether that entry is still needed. Additionally, for devices that process an ACL in order from top to bottom, a longer and more complicated ACL makes it harder to be sure you've placed new entries in exactly the right place.
    Protect the devices inside the border router and outside the firewall, and the outside interface of the firewall. People often forget that there are vulnerable devices sitting outside the firewall, including the Internet router itself. There is usually no reason for someone outside your network to access the devices outside your firewall. It is important to have filters on the router to prevent unauthorized users from being able to log in to the router, or to send management traffic to the router.

    For devices between the Internet router and the firewall (like the switch in the diagram above), the easiest way to prevent access from the outside is to use non-routed RFC 1918 address space. A device with private addressing can't be reached directly from the Internet. That said, if you're protecting a network that already has public, registered addresses on internal network equipment (it happens), it's absolutely critical that you create ACL entries on your Internet router preventing access from the outside to your network equipment addresses. Remember to include the firewall's outside interface (if using public addressing on it) as well. If, for some reason, access to these devices is needed from the outside, you should permit only the specific source IP address and protocol needed.

    Out-of-band (OOB) management offers another option for reaching your border router, or other network equipment, from the outside. If you are using an external company to monitor your infrastructure, the external company should be able to provide you specific IP addresses and protocols. You can allow those and block everything else.

    Filter the bogons. The bogons list represents an entire class of private and reserved IP addresses.

    According to Team Cymru, which maintains the most up-to-date list of bogons, "a bogon prefix is a route that should never appear in the Internet routing table. A packet routed over the public Internet (not including over VPNs or other tunnels) should never have a source address in a bogon range. These are commonly found as the source addresses of DDoS attacks."

    While we don't want to make the Internet router act as a firewall, the bogons list represents a simple way to eliminate obviously bad traffic at your network border, without the need for deep inspection, checking state tables, or complicated ACL entries.

    If you're filtering bogons, however, it's important that you keep your filters up to date. The bogons list can change as previously unallocated IP addresses are allocated by the Regional Internet Registries (RIRs).

    Block inbound traffic sourced from your own IP addresses. At the Internet router, it is important to block any external traffic that is sourced from an internal IP address. For example, if you have your own allocated block of addresses, you should not see external traffic sourced from one of your internal addresses. If you see traffic sourced from your own internal IP space trying to enter your network from the Internet, it suggests either that someone is spoofing your addresses to try to do you harm or a routing problem has occurred. It is important to block this type of traffic at the Internet router because it is very possible that traffic allegedly sourced from your internal IP space is only subject to limited filtering once it gets to your internal network.

In summary, when considering filtering at the Internet router level

    Don't mess with intricate filtering systems to block every suspicious IP address.
    Focus on blocking bogons and anyone trying to spoof your IP addresses.
    Protect the Internet router from outside traffic, and protect anything that sits between the router and the firewall.

Let Firewalls Be Firewalls

At the firewall level, your approach to filtering should be more fine-grained. As with your border router, first and foremost it is important to lock down access to the firewall itself. Unauthorized users should not have access to this device.

In addition, there are two principles for filtering at the firewall level:

    Default deny. A firewall is a security device and is designed to protect your assets. Your default position when configuring the firewall should therefore be to deny traffic. Don't think of the firewall as the device that permits all traffic through, except for the things you want to block. Instead, think of your firewall as the device that blocks all traffic, except for those things you choose to permit.

    Label everything. With firewall filtering, it is important to assume that someday a new firewall administrator will have to figure out what you did and why. I have seen incredibly complex firewall rule bases that were hard to understand because the logic and reasoning behind them were unclear (e.g., IP addresses in rules with no indication of what devices the IP addresses represented, with no labeling to tell you why the traffic was being permitted or denied). When it comes to firewall filtering, every new rule should take into account that a future firewall administrator must one day read these rules and understand them.

When you are creating new rules to permit inbound traffic, try to be as specific as possible. For example, if you know a particular server requires inbound traffic on just three TCP ports, don't create a rule permitting all inbound TCP to that server--create a rule allowing only the needed ports. While it may be easier to make the rule less specific "in case we need to permit more ports later on," this opens up that server to all sorts of traffic that it shouldn't be receiving, including malicious traffic designed to exploit vulnerabilities on all those TCP ports you left open.

Sometimes when a new server or application is being brought online, I've seen people say "We aren't sure which protocols are needed--just permit everything for now and we'll lock it down when we know exactly what we need to permit through." In my experience, that later lock down never happens. Think carefully about whether you want to put a device on your network without knowing exactly which protocols it's supposed to be using, and then allow traffic on any protocol to reach it.

At the same time, while you're being as specific as possible with your rule set, there are best practices you can use to make it easier on yourself. If you create an object group in your firewall to include the IP addresses of all devices of the same type, with the same security requirements (e.g., all your web servers or all your email servers), you can create a single rule permitting all the specific ports and protocols needed to the entire group of servers at once.

Similarly, if there's a particular service on your network that you need to permit a known set of external IP addresses or networks to access, you can create an object representing all of those external addresses and networks, and then create a single rule allowing those external devices access to the needed service. Remember the rule about letting future firewall administrators understand what you did and why you did it? Label that object so it's clearly understood what those addresses represent (e.g., "External B2B Partners" or "Remote Office Admins"). Moreover, if you are able to add comments to your rules, add a comment that explains what the rule is for, and whether there is an expiration date for that rule.

Finally, it is important for the firewall administrator to conduct a regular--at the very least annual--audit of firewall rules. Ideally, you would have the documentation and rule change requests in one file to ensure an easier audit. Rule requesters should be asked to verify that the rule they requested is still required, and unneeded rules should be removed.

To recap, when it comes to firewall filtering, it is important to

    Ensure that your default position is to deny traffic, not to permit it.
    Label everything as specifically as possible.
    Conduct regular audits.

By taking a layered approach to network border filtering, you can block the most obviously bogus or potentially harmful traffic at your Internet router, while allowing the firewall to do what it's designed to do, and inspect and block the remaining threats.

Wrapping Up and Looking Ahead

As attacks become more sophisticated, our team of network analysts at CERT increasingly finds Internet-facing services that aren't well deployed within a network. As Mark Langston wrote in his recent post on DNS Best Practices, many of these services make up the foundation for the security and operation of internal and external network applications.

This article is the latest in a series of blog posts offering best practices for these foundational structures. The series is intended to help government agencies and other enterprises address hidden sources of vulnerabilities within their networks. I published the first post in this series, Distributed Denial of Service Attacks: Four Best Practices for Prevention and Response. Mark Langston followed up with Six Best Practices for Securing a Robust Domain Name System (DNS) Infrastructure, and Timur Snoke wrote a post detailing Best Practices for NTP Services in March.
