4 Devastating Network Security Mistakes You Need to Avoid

Solutions Review details four devastating network security mistakes that your business must take steps to avoid making.

Keeping your network secure is crucial, but when your enterprise has hundreds or thousands of devices and connections on its campus, it can be difficult to ensure that your entire network is safe. If you doesn’t take the proper steps to securely manage and operate your network, it could suffer a major security incident that could have disastrous consequences for your business. That’s why it’s crucial to know about common mistakes that companies make regarding network security and how to avoid making them yourself. Below, we’ve listed four mistakes that your network security team must take steps to avoid.

Misconfiguring network devices

Network misconfigurations are a common source of headaches among network engineers — and they can spell big trouble if they aren’t addressed. You need to configure network devices and hosts so that they can communicate with each other securely, as well as be able to report data to your network management solution as needed. Otherwise, that hardware might allow for unauthorized access to your network and the data stored within it.

Not using encryption

Encrypting your network traffic makes it harder for external users to access sensitive data. If your company isn’t encrypting the data that travels across its networks, it risks having that data deciphered by bad actors if they gain access to your network. Encrypted network traffic makes it harder for data to be cracked open by those who don’t have the encryption key, lessening the risk that your data will be leaked outside your infrastructure.

Ignoring network access control

If your business doesn’t set access control regulations for its network, then sensitive corporate data will be open to unauthorized users. If your business allows external users to download data and files from your infrastructure onto their local machines, you want to ensure that only publicly available resources can be accessed from the outside. Even within its infrastructure, an enterprise should set role-based access regulations to ensure that only the proper employees are accessing specific data.

Leaving default network device passwords

If your network team isn’t in the habit of changing the default passwords of devices it onboards, then it needs to break this habit immediately. After installing a new device onto your network, the first order of business should be to change the device’s default password. This may seem like a no-brainer, but it’s a vital step in securing the network. Every device should have its own unique password (and preferably, other authentication methods as well) to make it harder for users to access them.
