What is a rootkit?
A rootkit is a software program that gives a malicious hacker control over a target computer system without the knowledge of the system’s legitimate owner or administrators. Once a rootkit is installed on a system, the attacker can use it to hide the presence of other software on the system that may be used to conduct further attacks, or to conceal their own activities. Rootkits can be used to intercept communications from the system, such as passwords or keystrokes, and can even be used to modify system files to insert malicious code that allows the attacker to gain permanent control over the system.
Rootkits are a type of malware, and are typically installed on a system without the user’s knowledge or consent. Once a system has been compromised by a rootkit, it can be very difficult to remove, as the attacker can use the rootkit to hide their tracks and keep their access to the system hidden. For this reason, it is important to take precautions to prevent rootkits from being installed on systems in the first place, such as by only downloading software from trusted sources and keeping systems up-to-date with the latest security patches..Extra resources
How can I secure my wireless network?
It’s no secret that wireless networking has made our lives much easier. We can now work from anywhere with an internet connection, and we can connect to our favorite online services without having to worry about cords and cables. However, as convenient as wireless networking is, it’s also very vulnerable to security threats. In this article, we’ll discuss some of the best ways to secure your wireless network and keep your data safe.
One of the most important things you can do to secure your wireless network is to use a strong password. Avoid using easily guessed words like “password” or “1234”, and make sure your password is at least eight characters long. It’s also a good idea to use a mix of uppercase and lowercase letters, numbers, and symbols.
In addition to using a strong password, you should also enable encryption on your wireless router. This will make it much more difficult for hackers to access your network, and it will help protect your data. There are two main types of encryption: WEP and WPA. WEP is the older of the two, and it’s not as secure as WPA. However, it’s still better than no encryption at all. If your router supports both WEP and WPA, we recommend using WPA.
Another good way to secure your wireless network is to disable the SSID broadcast feature on your router. This will make it more difficult for someone to find your network, and it will also make it more difficult for them to connect to it. If you need to enable the SSID broadcast feature for some reason, make sure to use a strong password and enable encryption.
You should also consider using a firewall to protect your network. A firewall can help to block unwanted traffic and keep your data safe. Many routers come with a built-in firewall, or you can install a software firewall on your computer.
Finally, it’s important to keep your router and computer up to date. Manufacturers regularly release firmware updates for routers that include security fixes. Make sure to download and install these updates as soon as they’re available. You should also keep your computer’s operating system and anti-virus software up to date. By doing these things, you’ll help to protect your network and keep your data safe.
