Network administrators and even individual computers are always concerned about security. They try to implement plans for every conceivable threat to network security. They often forget some of the fundamental threats.
Threats to network security
This article lists five lesser known threats to network security.
Users of the network or individual systems
The only way to combat this neglect is to educate users. In addition, whether it is a stand-alone computer or a computer on the network, users should be held responsible for problems caused by negligence.
Who is this person connecting via VPN? 12)
VPNs can be dangerous because they allow remote connection to the corporate network. While companies can provide notebooks configured for VPNs in some cases, in other cases it is possible to simply establish a VPN connection. The latter can be synonymous with misfortune if it is not watched. Contrary to the person’s intentions, the absence of adequate security measures can paralyze the network.
To avoid problems with VPNs, it is recommended to create a list of allowed machines and only allow these machines to connect via VPN. You can also set up an audit to check who connects to which machines and why.
Obsolete applications are a liability
In some networks, they continue to use an older version of applications (e.g. Outlook Express) because they are not willing to spend on upgrades. It’s about money and time. Older applications can easily run on your computer/network, but they pose a threat in that they can easily be supported by malicious people on the network. Old legacy applications also tend to disintegrate more than newer versions.
It is recommended to check the cost of the upgrade. If there is no problem, update or upgrade to a completely new application with similar functionality. For example, if you are still using FoxPro for DOS applications, you can upgrade to Visual FoxPro to ensure that your programs are up to date with the security installed.
Old servers running an impossible program
Almost all networks have one or more servers running older programs or operating systems. These servers cannot be updated because support is no longer available. Such servers seem to work well, but pose a major risk to the network. You know the server’s not down. But he can certainly be kidnapped by curious glances at the network.
The best method is to virtualize programs running on older servers. This way, you can try to update the programs. You can also save the entire program and decide on a replacement.
Local administrators are always a threat
More often than not, local administrators are people who get special privileges just to fix something on the computer. Once the troubleshooting is complete, administrator privileges should be revoked, but IT staff forget to do so. In this case, the local administrator account will invite the problem one or more days. The best way to deal with local administrators is to create profiles that run automatically.
