Why You Need A Multi Layered Approach To Security

Multi layered security

Firewalls are a well-known security essential, and we are certainly big fans, but did you know a firewall alone is not enough to keep your business safe? It is like building a fence around your house to keep the burglars out: You feel safe, private and secure… but the reality is, anyone with a ladder, enough motivation or ninja skills poses a real threat. That is why despite every networked business having a firewall in place, security breaches are increasing at an alarming rate – further protections are still needed.

Without these additional protections, once the firewall is beaten or bypassed it’s like a fox in a hen house. The bad guys are free to view and download files, make changes, and even take over your systems completely. That’s why computer security works best when it’s multi-layered. When one protection fails, the next layer kicks in to keep your business safe. And then the next, and the next…but that doesn’t mean you need CIA level security that gets in your way.

A few strategic, well-planned measures can provide all the protection your business needs to keep operating without costly downtime. While it’s cool to imagine a system so secure you’ll be opening doors with retinal scanners the reality is infinitely more usable and affordable. In fact, we’ll help you choose the perfect measures that blend invisibly into your existing processes, boosting security without affecting productivity. Take a look at some of our offerings:

Proper firewall device
While not enough by itself, your firewall is still your first line of defence. However, there’s a huge difference between the generic firewall that comes standard with your broadband router and a dedicated hardware firewall appliance. Our technicians will work with you to identify which firewall is suitable for your business.

Corporate Grade Antivirus Software
A free antivirus program might be ok for home use but do you really want a free program with no backup or support protecting your confidential business data and financial information?

Access restrictions
We’ll help you give employees access to only the files they need to do their job. It’s not a matter of trust, but rather one of security. If they were the one to accidentally let the attackers through the firewall, perhaps by clicking an email link, you’re then able to limit the damage. Without this added layer of protection, it’s relatively easy to access any and all files.

Encrypt confidential files
More secure than simply password locking a file, this uses a secret ‘key’ to scramble the files and their contents, so that when anyone else tries to view them all they see is incomprehensible nonsense. Our technicians can setup an encryption system for you so that approved users can use them normally while all files remain secure.

Backups
As nothing is totally 100% secure no matter what features you implement a backup is a necessity. Having your data backup on multiple removable devices (stored both locally and offsite) as well as a cloud based backup is a must.

DP Computing offers security services to make sure all our clients are protected and all their security products are operating at 100% efficiency. Threat analysis, prevention, management and response are all included so your focus can remain on growing your business and we’ll take care of the bad guys.

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”.

How Much Could A Ransomware Attack Cost Your Business?

How much is your data is worth? Information is probably the most valuable part of your business. Imagine if you lost your client database, accounting software, inventory management and any intellectual property you may own. How long will it take to recreate this data and how much money would you lose in lost productivity, staff wages and the time it takes to either recover or recreate the lost information?

Recently when the WannaCry ransomware spread through out the world, many businesses were suddenly forced to re-assess the value of their data: was it worth saving and what would be the ongoing costs of the attack?

If you don’t have a recent backup most ransomware attacks cost at least $US200 (if not a lot more) to get your files released and that is only IF the cyber criminals honor the payment and actually give you the decryption key (some even demand further payments). Meanwhile your business is still running and new client calls are still coming in and you may find yourself unable to operate with your systems down.

Paying the ransom may seem like a quick fix but:

  • There is still the downtime involved to restore your data resulting in lost productivity.
  • If word gets out that your data has been compromised you may find confidence in your business plummets and your existing clients head elsewhere.
  • The cyber criminals you pay, may now see you as an easy target and demand more money or target you for other scams and malware activity.
  • You may recover the data but is it compromised with other malware?
  • You may not get back all the data that has been lost.

So that $US200 ransom may end up costing many, many thousands of dollars!

How To Prevent Ransomware Attacks on your Business

Keep your systems up to date: Malware can take advantage of flaws in older versions of Windows and software – sometimes ones that have already been patched by Microsoft and third party vendors. To be protected businesses have to stay up to date with their patches & versions. To be up to date with Windows patches you need to be running a supported version of Windows. Delaying patches and updates puts your business at risk – we can help you keep you systems up to date.

Use corporate grade security software and firewall: Free software may be fine for low end home computers but if the worst happens you will get no support or help from a company providing free software. A firewall or UTM (unified threat management) device can also help block malware and ransomware infections. But whether it is a free or paid for solution the software (and any hardware devices) must be kept up to date.

Lock down employee computers: Very few staff will require full administrator access to your business network. With a higher level of permissions the more damage a person can do – either accidentally or by inadvertently installing malware. By locking down your computers you have a better chance of containing a malware attack to non-vital systems. Our expert computer technicians can design an access management plan that gives you best of both worlds – flexibility and security.

Educate your workplace: Most employees believe they are being cyber-safe but in reality it is quite different. Many malicious links and embedded malware have become harder to spot – and all it takes is a microsecond to click (and later regret it). We can work with your staff to establish procedures around checking links for authenticity before clicking, awareness around verifying the source of attachments and the importance of malware scanning and keeping systems up to date. We can help get the message through!

Have a solid backup plan: When ransomware hits, a connected backup = infected backup. Also a lot of cloud backup systems, such as Dropbox, immediately clone the infected files which also renders the cloud copy useless. The only safe backups will be the ones both physically and electronically disconnected. Our experts can set you up with a backup system that makes recovery simple.

Be proactive: The best way to avoid the costs of a ransomware attack is to prevent it from happening in the first place is with up to date antivirus software, regular systems updates and security audits. Remember, many businesses were able to watch WannaCry from the sidelines, completely unaffected and seized opportunities while their competitors were down.
