Dealing with remote access vulnerabilities in your network is important issues to consider. Remote Desktop Protocol (RDP) connection attacks rose for many years. RDP is a type of proprietary protocol which was developed by Microsoft. It allows a user to benefit from the graphical interface to connect with other computers.
RDP was designed to allow remote access to a LAN and that is why it request network connections. For establishing connections with systems of the network, some security issues occur. Although, connection can often results in concession security. Such as default port to be open or unlocked etc. Moreover, many other vendors like Microsoft have developed their own protocol for the remote access. So you get the benefit graphical interface to connect with other devices more securely.
Identify vulnerabilities in your network.
The real problem is, ports can be extremely vulnerable, or else easy for hacking. Common susceptible for login credentials like, Bruteforce POS attacks easily to any organizational networks. And it’s easy for them because login credentials are often shared by the user. And the worse thing is hackers can often gain access to the internal network when workstations are connected. And that’s are quite profitable to hacker and the opposite of an organization. Valuable data, money, security will compromise just occurring these facts.
In this article, I am going to discuss identify or dealing with remote access vulnerabilities in your network. Let’s begin.
Understand common attacks.
Possibilities of attack on your network can come from various ways. It has been seen that, many attackers don’t even attack for any specific reason. Or don’t know what they are attacking. They are just instancing of particular organization or networks.
So knowing and learning of different techniques will give you the perspective to being alert. Also, you can take necessary steps to avoid such as incidents.
Inventory your vulnerabilities. Make a full list of the potential vulnerabilities of your network. These will help you to determine what to do. But don’t forget to identify anything unknown your network. Being conscious of all your strength and weakness will help you to lessen the damage of hacking.
Don’t be any easy target.
Easier found is a general target of hackers. So stop advertising of wireless LAN. Change your Service Set Identifier (SSID) and turn off its broadcasting. Adjust your access point (AP) antennas and power level to avoid signal leakage to areas, if possible. Not all the areas, just those places where coverage is not disabled or not requires.
Use vulnerability scanning tools.
It will be a good option to scan your entire network. Many effective scanning tools are available for this job. These tools check your network’s security state. Such as, un-patched software, open ports etc. Some of them especially focus on a specific machine. Where, others scan your entire network. Here are few names of Use vulnerability scanning tools,
- The Microsoft Baseline Security Analyzer– Checks updates, configuration errors for all Microsoft products.
- Nmap– free scanning program for all necessary update and configuration errors of installing software. And other softwares are available in online.
Avoid easy convertible devices.
Most stolen or lost devices can be a threat to your network. Even Media access control addresses are still for work but it’s not that useful for the security. It’s easy for the converted device to pass this kind of security level. Moreover, another device consists of user name or passwords can change to work as new. These are also threats to your network.
Monitor AP configurations.
Once you configured AP, you should keep the process time to time. The AP should configure incorrect way. AP configuration is not too hard to do. One can easily reset on your office or organization. So actively track the configuration and ensure that it configured automatically. Before any event occurred and cause vast damages to your network.
But don’t place it anywhere that can be easy to access. Otherwise, your security will compromise too soon. Insecure location or unconsciousness of your employee can reset or replace it.
LAN encryptions like wired equal privacy are not strong. Instead of using built- in wireless, use virtual private network technologies. Like the IPsec along with triple DES. It will protect your data from several threats. For the greatest interpretability, try to avoid proprietary schemes.
Control your LAN traffic.
If your LAN is using for some specific purpose limited the access. Place specific packet filters on the wireless LAN. Limit the access to the specific section or access.
People think about only preventing the access of others to their network or computer. But the only reverting of access will not enough to avoid any actions. Like hackings, spreading computer virus or other unwanted events.
There are many other ways are available, how to deal with such as things. It can’t say you will 100% secure after taking necessary steps. But you have to maintain these stuffs. Many organizations, service centers are now offering services to deal with this type of technologies. You can hire them online or personally for secure you net works. InnovIT is working on finding vulnerabilities and offering you a safe and secure solution especially for SMB business. So that is all for today, hope now you are able to deal with remote access vulnerabilities in your network.
