10 bad habits network administrators should avoid at all costs

10. Poor monitoring discipline

Poor monitoring discipline is an easy habit to pick up, as networks have grown in size, complexity, and geographic distribution, according to Patrick Hubbard, head geek at SolarWinds. The growth of the cloud has also made it more difficult to pinpoint the root causes of performance issues. And often, network admins are siloed from server admins, storage admins, and others, with little cross-discipline monitoring.

"Monitoring across multiple disciplines instead of the traditional silos can provide a cohesive view across an organization's IT spectrum, and thus ridding the bad habit of the old way of monitoring can make root cause analysis much more efficient and accurate, reducing costs in the process," Hubbard said. "For network administrators to be most effective at their job, they need to expand current skillsets to effectively monitor hardware, networks (i.e. NetFlow and syslog), applications, virtualization, configurations, cloud and even containerized workloads."

8. Allowing ports and protocols outbound to the internet

Allowing access to any port and protocol out on the internet is a bad idea, according to IT consultant Ben Piper. "Allow only the standard tcp/80 for http, tcp/443 for https, and whatever else you know your organization requires. Block all else," he advised. Also, because some malware uses SSH (tcp/22), network admins should only allow it per-destination IP address, Piper said.

9. Using scripting to hack at automating networking

"Especially as IT continues to modernize at a rapid pace, one bad habit that network administrators need to break is incorrectly using scripting to hack at automating networking," said Cortney Thompson, CIO of Green House Data. "While scripting can significantly ease the burden of network administration, it must be done within a framework, as opposed to applying a hodgepodge, or trying constantly bridge legacy code gaps."

A DevOps model can offer a more efficient and scaleable direction for network automation, Thompson said. "This allows considerations for aspects of tooling, code pipeline, immutable infrastructure, upgrades, and resilience," she added." Applying a DevOps model to networking helps realize the DevNetOps benefits which support continuous integration and continuous deployment."

6. Failing to keep skills updated

With the constant pace of change in the tech industry, if an IT professional is not constantly learning, their skills are getting stale, according to Peter Tsai, senior technology analyst at Spiceworks. "Network administrators who become complacent in their jobs without exploring new ideas, methodologies, or technologies run the risk limiting their career opportunities in the future," Tsai said. "Even if hands-on training with emerging tech is not available on the job, IT pros can combat getting left behind by taking training courses, pursuing certifications, and setting up home labs to gain more knowledge and experience."

7. Using command-line interface to troubleshoot your networking

Network administrators need to get away from logging into the command-line interface (CLI) in their network equipment to manually troubleshoot network performance problems, according to Justin Ryburn, a technical marketing manager at Kentik and former network engineer. "Instead, they should build tools that leverage internal and external APIs and databases to provide them with the performance alerts and information they need," Ryburn said.

4. Believing that your network is impenetrable

Over-confidence in the safety of your network can lead to a hack or a security threat gone unnoticed, "Sometimes network administrators get too caught up in putting out immediate threats and cyber concerns that they don't check the overall effectiveness of the entire security system,".

5. Experiencing alert fatigue and short-term thinking

Alert fatigue is the term used to explain the phenomenon of network administrators and other security analysts not responding to security alerts simply because they receive so many each day. "Too many incoming alerts are creating a general sense of overload for anyone in IT," said Christopher Ensey, COO at Dunbar Security Solutions. "Security is an area where we are seeing explosive growth in new tools and the volume of notifications is exponentially growing. Network administrators need to implement a better means of filtering, prioritizing and correlating incidents."

2. Doing everything manually

When you automate processes, you get rid of a dull routine, improve efficiency, and have more control over the entire IT infrastructure.

3. Making changes without logging them in change control
It can be easy to say "I'll just make this one little config change," said Jim Frey, vice president of strategic alliances at Kentik and former network industry analyst. "But when someone else is trying to figure out why something is broken a few days or weeks later, it's essential to understand what changed versus the expected baseline. That's why having a change control process is critical."

10 bad habits network administrators should avoid at all costs

Network administrators are responsible for protecting enterprise data from a number of security threats. Here are 10 bad habits they must avoid to be most effective.

1. Failing to update policies frequently

Policies are living, breathing elements of networking, which need to be revisited regularly to address the internal and external changes for monitoring and managing the network, according to Kyle Gingrich, vice president of IT & Certifications at Skillsoft. "Networks are combinations of multiple third party equipment and applications, so as network administrators make changes, those components policies may be impacted as well," Gingrich added.
