Relentless cyber criminals, disgruntled current and former employees and careless users can bring down your computer networks and compromise data. Multiple layers of hardware and software can prevent threats from damaging computer networks and stop them from spreading if they slip past your defenses.

The most common threats that can affect your systems:

  • Malicious programs
  • Contact attacks by hackers
  • Denial of Service (DoS) and Distributed Denial of Service Attacks (DDoS),
  • Data theft and then held for ransom.

 

These network security fundamentals are vital to downtime prevention, government regulation compliance, reduced liability and reputation protection:

 

  •  Keep patches and updates current

Cyber criminals exploit vulnerabilities in operating systems, software applications, web browsers and browser plug-ins when administrators are lax about applying patches and updates. In this case, keep an inventory to make sure each device is updated regularly, including mobile devices and network hardware. Make sure Windows and Apple computers have automatic updating enabled.

  • Use strong passwords

By now, users know not to write their passwords on Post-It Notes and plaster it to their monitors. However, there’s more to keeping passwords secure than keeping them out of plain sight.

The definition of a strong password is one that’s difficult to detect by humans and computers. Above all, a strong password should be at least 6 characters, preferably more, and uses a combination of upper- and lower-case letters, numbers and symbols.

Password tips:

  • Avoid using nouns or foreign words.
  • Though easy, never use any phrase that relates to your name, nickname or even pets
  • Don’t make it easy for someone to guess by trying your mobile number or street numbers
  • Choose a phrase that means something to you, take the first letters of each word and convert some into characters.

Hackers are also known to impersonate tech support to get people to give out their passwords or simply look over users’ shoulders while they type in their passwords.

 

  • Secure your VPN

Data encryption and identity authentication are especially important to securing a VPN. Therefore, any open network connection is vulnerable to hackers and they can exploit it to sneak onto your network. Moreover, data is particularly vulnerable while it is travelling over the Internet. Review the documentation for your server and VPN software to make sure that the strongest possible protocols for encryption and authentication are in use.

Multi-factor authentication is the most secure identity authentication method. The more steps your users must take to prove their identity, the better. For example, in addition to a password, users could be required to enter a PIN or a random numerical code generated by a key-fob authenticator every 60 seconds could be used in conjunction with a PIN or password.

It is also a good idea to use a firewall to separate the VPN network from the rest of the network.

 

  • Manage your staff privileged access to company info

Company staff snooping on things they shouldn’t is a serious threat to your business and controlling certain company data from prying eyes should not be overlooked. Surprisingly, about half of business companies allow their employees permission to confidential and information that is not within their job scope. When an employee’s job changes, make sure the IT department is notified so their access privileges can be modified to fit the duties of the new position.

 

  • Have any inactive accounts? Clear them away

Once the hackers find any abandoned accounts that once belonged contractors or past employees, they will disguise their activities and use that information as a disguise. It is important that all companies should destroy all previous employees that resigned or were laid off. There is software on the market today that clears inactive accounts on large networks.
