**INTRODUCTION
It’s human nature to pay attention to the problems that are big and flashy, attracting lots of interest, such as advanced persistent threat (APT) groups—state-sponsored attackers. APT-linked attackers have compromised major retailers, financial institutions, and even government networks. But when we focus all of our attention on APTs and other headline-generating activity, we miss basic issues. Even though you have new firewalls protecting your system and powerful traffic-monitoring devices, if you don’t keep up with the bread and butter of your security responsibilities, you’re leaving many chinks in your system’s armor. Neglecting the basics, like keeping your systems updated, can lead to serious consequences.
Consider this example: suppose you’re an information security manager at a medium-sized e-commerce business. You’ve set up firewalls to block incoming traffic except for traffic to internet-facing services on systems in your demilitarized zone (DMZ). You’ve turned on egress filtering to block unauthorized exit traffic. An antivirus is on the endpoints, and you’ve hardened your servers. You believe your system is safe. 
But an old web service is running on an outdated version of Tomcat on a Linux server in the DMZ. It’s a relic from an ill-advised foray into selling some of your company’s valuable proprietary data to selected business partners. The initiative failed, but because you made some sales, you had a contractual obligation to keep that server up for another year. At the end of the year, the project was quietly shuttered, but the server is still running. Everyone has forgotten about it. But someone on the outside notices it. An attack comes in from a compromised server in Moldova, and your unpatched Tomcat server is vulnerable to a five-year-old Java issue. Now the attacker has a foothold in your network, and all your protections couldn’t stop it. Where did you fail?
This guide demonstrates the value of strong information security fundamentals. These are the most important components of a successful informa…
