Ten most common enterprise security mistakes that admins still make

Securing an enterprise is a never-ending task for desktop admins, but many are still making the same security blunders that have caused trouble in the past.

Failing to recognize that computing as we know it is changing is the basis for many security problems. Information system complexity is growing by the minute, and there’s more information in more places than ever. Still, many desktop administrators are proclaiming that their current state of information security is “good enough” and ignoring very real security threats. If only it were that simple. Here are 10 of the most common information...

security mistakes that admins are still making:

1. Tolerating weak passwords

From operating system logins and file encryption to Web accounts and beyond, weak passwords are arguably the most nonsensical, yet simplest security flaws to fix. Come up with a password policy, apply it across the board, periodically check for weaknesses, and be done with this issue once and for all.

2. Giving security policies too much credit

Security policies are great. They set everyone’s expectations, please the auditors and regulators and serve as a fallback when something goes awry and ends up in court. Sadly, many managers assume that just because the rules have been documented that everyone suddenly knows about them. Make sure that all employees are on board with these rules, and they’ll enforce themselves.

3. Relying too heavily on technology

As with policies, security technologies are not a silver bullet, either. Sure, firewalls, antivirus and encryption sound cool and can serve the business well, but they’re only the beginning of an information security architecture. People and processes are also factors in this equation. Leave one out and most technology benefits won’t be fully realized, if not completely negated altogether.

4. Connecting to random WiFi hotspots

We’ve come to expect a wireless signal wherever we are. Many people don’t think twice about hopping onto a random (and unprotected) wireless network just to get some work done. But a quick email is no excuse. That’s all it takes for someone with ill intent to capture a user’s login credentials and work his way onto your wireless network.

5. Ignoring the need to encrypt hard drives and mobile storage

Simply encrypting workstation hard drives can eliminate a huge portion of a company’s information risks today. Given the huge bang for the buck ofwhole-disk encryption, many admins -- especially in small and medium-sized businesses -- have looked the other way.

6. Trusting users to keep endpoints in check

More and more environments are making users responsible for patching, data backups and even ensuring their antivirus protection is current -- talk about a great way to set everyone up for failure. Employees and other network users should never be held responsible for security. Sure, employees can be a good line of defense, but do whatever you can to put the proper controls and processes in place so that they’re not held responsible for IT's daily tasks.

7. Assuming that patches are under control

As far as we’ve come with patching, there are typically hundreds of missing patches on both workstations and servers in any given environment. In many situations, admins are unaware of specific hosts on their network or whether their patch management system is reporting the current status properly. Missing OS and third-party application patches can lead to breaches you might not ever know about.

8. Performing simple vulnerability scans and checklist audits

Many admins simply don’t acknowledge what’s really at risk with their systems. Therefore, when performing security assessments, they tend not to dig deep enough, often enough. Exacerbating this problem is the underlying assumption that compliant equals secure. But it never has, and it never will.

9. Assuming that security incidents will be highly visible

Thanks in part to the media and Hollywood glamourizing hack attacks and data breaches, management often expects that these incidents are going to be glaringly obvious. However, it’s almost always the opposite. The lack of perceived risk doesn’t mean there is no risk. We have to be careful not to fool ourselves into thinking that all’s well because there’s no bleeding.

10. Not balancing security with convenience

One of the cornerstone principles of good information security is balancing security with usability so that it doesn’t get in the way of day-to-day business. Yet, either by design or the law of unintended consequences, security controls often get in the way of users, who then find ways around it. Writing passwords on sticky notes is just the beginning.

Long after these security weaknesses become well-known, they often continue to be ignored, so it’s important to address them before you have to. As Ayn Rand once said, “We can evade reality, but we cannot evade the consequences of evading reality.” The power of choice is a wonderful gift we’ve all been given -- use it wisely, and you’ll do just fine.
