BECOMING CYBER SECURE AND MALWARE Does your computer have security programs on it? Are they up to date? The best ways to steer clear of viruses and malware are to use an industry-leading anti-virus software solution. There are many types out there, and they don’t have to break the bank, but having a level of defense can go a long way. On your anti-virus software, enable the “auto update”, “auto-protect” and “personal firewall” to ensure you always have protection in the background and that it stays updated. Also, when possible use “whitelisting” solutions. Unlike most of the anti-virus solutions that use a “blacklist” to identify malicious files, these solutions allow you to create a “whitelist” of programs and applications that you explicitly allow to run for your day to day business. Everything else is automatically blocked providing a higher level of security. TIP #5 – MAKE YOUR SYSTEM LESS “VULNERABLE” Did you know that majority of attacks rely on un-patched operating system vulnerabilities? Protecting your computers against such attacks and making them less vulnerable is as simple as turning on “auto updates” for your computers operating system. If you use Microsoft Windows, this can be done by choosing to “automate installation” of all “important updates”. Similarly, other software applications on your PC like Adobe should also be configured to check automatically for updates. TIP #6 – DON’T FALL FOR ‘FREE’ USB DRIVES Who doesn’t like free stuff! It is nearly impossible to go around a trade fair today without walking out with a bag full of “free” USB drives. While there is no harm in collecting them and handing them over to your kids as a toy, it might not be a very good idea to actually plug them in your home or work computer. If you don’t trust the source of the USB drive, don’t plug it in. These drives can very easily be used to carry and deliver a malware or virus onto your computer, allowing someone else access to your important information. In fact, this technique was used to perpetrate the “worst breach of U.S. military computers in history”. It started in 2008, with a USB flash drive infected by a foreign intelligence agency left in the parking lot of a Department of Defense facility at a base in the Middle East and impacted the network of United States Central Command. It took 14 months to clean the network and the systems. A recent study was done to determine the success rate of this attack vector. They dropped USB drives in a public parking lot of government buildings and private contractors. 60% of the people that picked one up plugged the device into their office computers. If it had a logo on it, 90% plugged them in. These people didn’t know where the drives came from but used them anyway. Thankfully it was just a study, but can you imagine if the impact if it were an actual attack? TIP #7 – AVOID BEING RANSOMED BY “RANSOMWARE” Have you or someone you know been a victim of “Ransomware”? As the name suggests, “Ransomware” is a computer malware that “locks” all your data on your computer by encrypting it and demands a ransom payment to restore it. Usually the ransom amount is a few hundred dollars, unless you are an institution like a BY:ANURAG SHARMA CISA, CISSP, CRISC, MBA, IS A PRINCIPAL WITH WITHUMSMITH+BROWN hospital, a local police department, etc. in which case the ransom amount can run to thousands of dollars. Just in the first three months of 2016, these attacks increased tenfold over the total entire previous year, costing victims more than $200 million. The easiest way to minimize the impact of a “Ransomware” attack is to immediately disconnect the infected machine(s) from the network, reinstall the operating system (yes just cleaning with an anti- malware software is not recommended) and restore from your last good backup copy. That brings us to the key question: Do you backup your laptop or desktop daily? It’s never too late to start. How else can you protect yourself from Ransomware? And, if necessary, pay the ransom to get your files back. TIP #8 – IS PUBLIC WI-FI REALLY SAFE? Public Wi-Fi is great. You can sign on while on the go – from the coffee shop, hotel or airport. But, using unsecured, public Wi-Fi can come with risks. Hackers can act as the “middle man” between you and the connection point, seeing all traffic and files you’re sharing. How can you stay secure? • Always use VPN connection when possible. This will ensure a secure conne
