4 Ways To Protect Your Firm Against Unknown Threats

Unknown threatsProtecting your business against the latest IT threats should always be a top priority. Updating your antivirus and keeping your operating system and applications up to date is a great way to start. What happens though, when a threat appears at your door before security firms have had a chance to catch it?

A security threat that exploits a previously undiscovered vulnerability is known as a zero-day threat. The name “zero-day” is designed to show how long since the vulnerability was discovered and also indicates that system developers have had zero days to fix it.

A newly discovered attack might be included in a computer virus or worm. This will allow it to spread far and wide, while inflicting the maximum amount of damage possible. When spread successfully, a new exploit has the potential to reach hundreds of thousands of computers before an operating system or anti-virus update can even be issued.

Here are 4 ways to help protect your business or lessen the damage from an unknown or  zero-day attack.

1. Preventative security

The number one way to mitigate the damage from any attack is to prevent it from happening in the first place. Maintaining a good firewall and up-to-date security system is the best way you can take to ensure the security of your system.

A firewall, which monitors traffic in and out of your network, reduces unauthorised entries and exits over the network. Even without knowing the exact nature of the attack, suspicious activity can be stopped.

The same is true of modern security software. Even when it can’t identify the specific zero-day threat from its virus database; it can often identify malicious intent from learned behaviour in the system.

2. A Locked Down Network

Should a zero-day threat make it into your network, our next goal is to limit its effects. By restricting user access to only essential files and systems we can limit the damage done to the smallest area. Good security policy dictates that each account should only have full access to the systems needed to complete the user’s job. For example, users from the accounts department shouldn’t have access to sales department databases – see our blog article here on this area of security.

In this way, the damage of a single compromised account is limited to only the network area it has permissions to. Limiting the impact makes it easier to recover if the worst happens.

3. Good Data backup

Whether your entire network has been exploited or only a small area has been affected; good data backups are a must and are your protection against major long term damage. Having a good backup means having the procedures in place to create regular backup copies and also regularly test those backups to make sure they can be restored at a later date.

Reliable and well tested backups are worth their weight in gold. They allow you to sleep well at night knowing your data is safe and your system can be recovered.

4. Intrusion Protection

While the precise methods of a zero-day exploit can’t be known in advance, a network intrusion protection system (NIPS) can monitor your firms network for unusual activity.

The advantage of NIPS over a traditional firewall and traditional antivirus software is that it does not rely on checking software against a known database of threats. This means it does not need updates or patches to learn about the latest attacks. NIPS works by learning the day-to-day patterns of network activity across the network.

When traffic or something out of the ordinary is detected, action can be taken to alert system administrators and lock down the network.

NIPS protects against threats introduced to the network from both external and internal sources.

Full Cover Protection

Used in combination these techniques can prevent, protect, and mitigate against the kinds of threats that even the top security firms don’t even know of yet.

Why Your Business Needs a Firewall With Unified Threat Management

Unified Threat Management - FirewallUnified Threat Management (UTM) is a special kind of firewall solution focused on proactive protection. Consider it like a team of virtual bodyguards that stand at the door between your business and the internet, keeping trouble out while your legitimate traffic can come and go normally.

With the increasing number of connected devices in your business network and the different ways your employees can now connect, it is more important than ever to set up dedicated security systems that give integrated protection. UTM is a series of solutions that work together, simultaneously layering your protection across the board. We’ll cover the four main inclusions here and show exactly what they can do for your business.

Robust Firewall

Put simply, a firewall keeps an eye on all the data coming in and out of your network and looks for anything abnormal. While every home PC comes with a software firewall built in, those ones pale in comparison to what a UTM firewall can do. Remember the team of virtual bodyguards? Imagine the home firewall asking nicely if the data should be doing that, while the UTM slams the data to the ground and demands answers. Its job it to make sure the data entering your network is safe, that it is not part of a cyber-attack, and that in the rare event your network becomes infected, your servers aren’t being used to attack another business.

Anti-virus Where it Matters

With so much new malware being released daily, it’s easy to fall behind in updates and discover you’ve been infected. Your employees are likely doing their best, but manually scanning each file can be exhausting and time-consuming. Your UTM anti-virus is built into the firewall, ensuring known or suspicious malware is stopped at the door removing any risk. Clearly that is the best outcome possible and will allow your employees to work at maximum efficiency, while you can run your business with confidence.

Spam Blocking

Most cyber-attacks come via email these days, with either an attachment or a link. Once clicked, the malware wreaks havoc in your network. Obviously, your employees are smart enough not to open random attachments/links, so hackers use phishing emails. These are emails that look legitimate and may refer to vendors you use, financial services you have accounts with or even seem to be from other employees. Your UTM strips down each email and checks it against high-tech legitimacy markers. If it sees anything suspicious, the email is marked as spam and either held for review or bounced away.

As the phoney emails are blocked, your employees never see the emails so they can’t accidentally open up the network for attack. While the UTM is monitoring for phishing/fake emails, it’s also culling out the general spam that clogs up inboxes. Employees will no longer have to spend precious minutes each day wading through the junk, and the likelihood of missing an important customer email has greatly dropped.

Content Filtering

In a perfect world, your employees would only access work-related sites and do work-related things online. Content filtering can help you limit the risk they’re bringing into your business via their Internet browsing. Your UTM can be set to restrict sites that infect computers, such as adult content, gambling or illegal downloads. It can also be used to restrict access to social media sites like Facebook, Twitter or Pinterest, either during work hours or completely. It’s up to your policies how much you’d like to filter and whether to add any flexibility. Some businesses allow social media during lunch breaks or have special reward hours each week. Simple tweaks like this can increase productivity overnight and give you the security you’re looking for.

You can see how a layered security solution like UTM provides a space for your business to thrive, where systems are secure, employees are able to maintain efficiency, and cyber problems stay outside the doors. The way the layers work together is more effective than a patchwork of separate systems, and a UTM is much easier to configure and maintain.

The True and Unexpected Costs of Being Hacked

Security BreechThere are the normal costs everyone associates with a computer breach, like employee downtime and the costs associated with getting your network and computers fixed. But really, most businesses that haven’t been hit with a security incident view it as more of an inconvenience than a bottom-line cost. For those businesses who have come out the other side though, it’s a very different story. They know from firsthand experience that the hidden and ongoing costs of a data breach can be crippling and that IT security exists to protect your business on multiple levels. All those surprise costs that spiral out of control are why most businesses close down after a cyber-attack. Here are a few of the hard, but common cold hard realities of life after a hack.

Raiding the budget to reduce downtime

From the moment a cyber-attack compromises your system, things can get expensive, and the longer the attack goes, the more it costs. Latest statistics reveal most breaches aren’t identified for around 191 days and then it can take on average another 66 days to fix and contain the damage – during this time you are cleaning PCs, mobile devices, laptops, servers and even entire networks. Add to this the fees for IT professionals to fix everything up, the costs for new hardware and software to help prevent future incidents  and all the hours/days/weeks when your business is struggling with downtime, businesses will quickly exhaust any emergency funds they have.

The long arm of the law

Depending on what data was stolen and how you handled the situation, you could be liable for fines into the millions. If medical data or legal files are leaked a particularly messy scenario may occur with fines coming from multiple sources.

New privacy laws also mean businesses are liable for large fines if they don’t disclose a data breach. Where this gets trickier is that the burden is on your business to know exactly what data has been stolen or illegally accessed, so that you can report it before the fines stack up. This means that even if you were able to fix up the systems yourself, you will still need to hire an expert who can identify exactly data what the hackers took or accessed.

Customer retention measures

In a double crush to your bottom line, not only does your business bear the cost of fixing the hack and your future income takes a hit as customers lose trust and leave. To offset this, many businesses need to spend more on advertising and public relations just to ensure they survive to fight another day.

The data breach disclosure may still come up in search results for many years to come. The more negative publicity your breach attracts, the more you’ll need to spend on customer retention.

All your secrets exposed

While you may not have high level secrets to protect, your business does have data that you would like to keep to yourself. Hackers love going after those juicy tidbits, and the more closely you guard them, the more attractive they are. While large corporations would be big enough to keep their competitive edge after the breach, your business success relies on at least some information staying secret (databases, client info, financial records etc).

But simply avoiding a breach doesn’t cost much at all…

The thing is, it’s not expensive to stay on top of it all and keep your business protected. For a low monthly fee, we can reverse the entire scenario and secure your systems against the unknown. That means no need to raid other department budgets in a panic, pay crippling fines and make embarrassing public announcements.

DP Computing can help with making sure your systems have the latest security patches and your anti-virus knows the latest tricks to watch for. Our technicians implemented a firewall or UTM device to build a virtual fortress around your business that keeps the bad guys out while letting you thrive. Whatever your needs are, both now and moving ahead, we’re here to help keep you safe.

Eleven Best Security Practices To Stop Ransomware

Ransomware and most malware attacks start in two main ways. A booby-trapped email with a malicious attachment or via a compromised website; which then work their way down to your endpoints and servers.To stop these attacks, it is critical that you have a multi layered approach to security.

This starts with a training your employees and patching your devices right through to cloud based malware filters, dedicated hardware firewalls and corporate grade security applications on each device.

The eleven best security practices to apply now are:

  1. Employee training
    Regular training for employees is essential. Employers need to inform their staff on what to look out for and don’t trust the contents of every email they receive.
  2. Patch early, patch often
    The sooner you patch Windows the fewer holes there are for ransomware to exploit.
  3. Backup
    Backup regularly and keep a recent backup copy off-line and off-site. Offline and off-site means ransomware can’t get to it. With recent backups data loss can be minimized.
  4. Implement corporate grade security software
    A free antivirus program might be ok for home use but do you really want a free program protecting your confidential business data and financial information?
  5. Install a firewall or UTM
    You probably don’t just rely on a cheap door lock on the front door of your house so why rely on a basic firewall on the electronic entrance to your business?
  6. Enable cloud based email filtering
    Don’t rely on your local antivirus software detecting and stopping malware within your email application. Block it before it even enters your network by using using a cloud based filter – one that uses multiple filters is even better.
  7. Enable file extensions.
    Enabling extensions makes it much easier to spot file types that wouldn’t commonly be sent to you.
  8. Disable Macros
    Don’t enable macros in document attachments received via email. A lot of infections rely on persuading you to turn macros on, so don’t do it!
  9. Be cautious about unsolicited attachments
    If you aren’t sure – don’t open it. Check with the sender if possible.
  10. Admin Login Rights
    Don’t have more login power than you need. Having administrator rights may bake things easier for administration but they also give malware free ranges on your computer and network. An infection which may be able to be contained to one device could become a network disaster is the malware exploits admin rights.
  11. Keep applications up to date.
    Stay up-to-date with new security features in your business applications
    For example Office 2016 now includes a control called “Block macros from running in Office files from the internet”.
