21 Feb Don’t Pay the Ransom – 8 Tips to Protect Your Business
Ransomware: a type of malicious software designed to block access to a computer system until a sum of money is paid.
You might have not been affected by it but have mostly likely heard of it as the risk continues to rise for companies of all sizes. These threats pose numerous issues for businesses from financial loss to loss of productivity.
Ransomware typically targets computers and servers running Windows Operating Systems, although attacks that target Mac operating systems are increasing. As we continue to be more reliant on our mobile devices, infections are also becoming more common on these platforms.
Naked Security by SOPHOS has put together 8 tips to help protect yourself from being a ransomware victim (for the complete article visit https://nakedsecurity.sophos.com/2016/03/24/8-tips-for-preventing-ransomware/)
1. Back up your files regularly and keep a recent backup off-site. The only backup you’ll ever regret is one you left for “another day.” Backups can protect your data against more than just ransomware: theft, fire, flood or accidental deletion all have the same effect. Make sure you encrypt the backed up data so only you can restore it.
2. Don’t enable macros. A lot of ransomware is distributed in Office documents that trick users into enabling macros. Microsoft has just released a new tool in Office 2016 that can limit the functionality of macros by preventing you from enabling them on documents downloaded from the internet.
3. Consider installing Microsoft Office viewers. They allow you to see what a Word or Excel document looks like without macros. The viewers don’t support macros so you can’t enable them by mistake, either.
4. Be very careful about opening unsolicited attachments. Most Windows ransomware in recent months has been embedded in documents distributed as email attachments.
5. Don’t give yourself more login power than necessary. Don’t stay logged in as an administrator any longer than necessary. Avoid browsing, opening documents or other regular work activities while logged in as administrator.
6. Patch, patch, patch. Malware that doesn’t come in via document macros often relies on bugs in software and applications. When you apply security patches, you give the cybercriminals fewer options for infecting you with ransomware.
7. Train and retrain employees in your business. Your users can be your weakest link if you don’t train them how to avoid booby-trapped documents and malicious emails.
8. Segment the company network. Separate functional areas with a firewall, e.g., the client and server networks, so systems and services can only be accessed if really necessary.
