Now that we've had a look at layered security, it's time to talk about each layer individually to figure out the steps you should take to secure your network. First and foremost is the DNS layer, the first "wall" of security that protects your network from attacks. DNS 101 Domain Name System (DNS) is used like a phonebook to help your computer find websites by translating a domain name to a website's IP address. For example, the domain name www.fortinet.com is translated to the IP address 66.171.121.34, which lets your computer successfully... [Read More]

A: Email is totally insecure. Despite this fact, it is relied upon for some of our most critical personal and business communications.

Security was not as paramount a concern as it is now; it never made it into the protocol. Changing this has been an uphill struggle due to the sheer number of mail servers and users who rely on them. Even today, by default, email is sent in plain text (if both servers do not already use... [Read More]

A: Reset your password and security questions, run a virus scan, and hope for the best. Beyond the basics, there are a few more considerations when your Gmail (or any other account for that matter) has been breached. Google offers two-factor authentication, enabling this should be one of your first steps. Two-factor authentication requires anyone logging into your account to not only know your username and password, but also retrieve a time sensitive token. This security token is usually a 5 digit number sent to your cell phone or your... [Read More]

Having the most up to date patches installed can, more often than not, resolve a majority of basic security vulnerabilities. Patch management is as fundamental to your security posture as changing the oil in your car. Being proactive about it is the veritable low hanging fruit when it comes to filling in security cracks. Adding a basic firewall on your network can make... [Read More]
