In the second of a series of blog posts around IT security Gavin Brown, Pinnacle’s Head of IT Support, gives his top tips on protection against Ransomware!
Following the recent global spates of Ransomware attacks here’s a protection checklist to ensure your business minimizes the threat of such attacks. Whether you are a large organisation or small-to medium size any business connected to the internet is at risk.
Ransomware blocks access to your computer and demands money before allowing you back in.
An effective Network security plan should include:
Security companies stress that educating staff is key in protection from Ransomware.
Staff should know how to avoid and prevent attacks and how to react if an attack should break through.
This is the process by which you program your computer to allow certain applications and not to allow others.
Malicious software is blocked when it attempts to operate.
3. Safely browsing the Web
Restrict access to websites that are likely to contain threats.
4. An operational Backup system
Backup systems can save you in the event of a security breach.
In an ideal scenario, you can restore data and start afresh.
5. Access Control
Limit access to business critical data.
This will limit the spread of Ransomware around your network if you are attacked.
6. An IT Partner
Even if you choose to manage your security system In-house, it is important to have a relationship with an IT Partner should you ever need an expert’s attention quickly.
You’ll also benefit from an IT company’s continuous research.
7. Network Security Software
A Network Security solution will make your life a whole lot easier.
Web Security companies regularly release new products to battle criminal developments in Malware. Pinnacle’s IT experts currently recommend the Sophos product ‘Intercept X.’
8. Patch Management
It’s vital to keep your IT environment updated.
Important patches need to be added continuously. Turn your computer off periodically to allow patches the chance to update
9. A Disaster Plan
Even with a watertight security system, it is highly likely your business will come under attack.
If a computer is compromised, cut its internet connection, disable shared drives and shut off power. Seek expert advice on what your plan should be if this happens – it will depend on your backup system and the nature of the ransomware.
10. Root Cause Analysis
Learn from the mistakes of yourself and others.
IT experts soon learn where attacks originate and the common mistakes that people make in allowing attacks in. Contact your IT Partner or attend a webinar.
The three most common methods that Ransomware is distributed:
Decide if you want to outsource your network security plan or if you would like to deal with it In-house. The decision can be made with the advice from experts and will depend on the size of your network and the level of risk.
