What is adware?
Adware is a type of software that automatically displays advertisements on a user’s computer. The ads may be in the form of pop-up windows, banner ads, or text links. Adware is generally considered to be a type of spyware because it gathers information about a user’s web browsing habits in order to target them with more personalized ads. Some adware programs can be difficult to remove, and may hijack a user’s web browser or track their online activity without their knowledge or consent.
Adware is a controversial form of advertising because it can be intrusive and difficult to get rid of. Some people believe that all adware is spyware and should be avoided, while others see it as a necessary evil that comes with using free software. There is no doubt that adware can be annoying, but it is important to remember that not all adware is created equal. Some programs are more benign than others, and there are even some that can be useful.
Whether or not you believe that adware is a good thing or a bad thing, it is important to be aware of what it is and how it works. That way, you can make an informed decision about whether or not to use programs that come with it.Visit Them
What is a denial of service attack?
What is a denial of service attack?
A denial of service attack (DoS attack) is an attempt to make a machine or network resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an internet site or service from functioning efficiently or at all, temporarily or permanently.
DoS attacks typically exploit weaknesses in either the application layer or transport layer of the OSI model. Commonly used attack vectors include SYN floods, Ping of Death, teardrop attacks, Smurf attacks, and buffer overflow attacks.
DoS attacks are usually aimed at a specific victim or group of victims, and are often carried out as a form of protest or retaliation. However, they can also be done for the purposes of distraction, to take attention away from another ongoing attack, or to simply disrupt internet activity in general.
There are a variety of denial of service attack tools available, both open-source and commercial. The most common DoS attacks are usually carried out with simple tools like ping or traceroute. However, more sophisticated attacks may make use of more sophisticated tools like LOIC (Low Orbit Ion Cannon), HOIC (High Orbit Ion Cannon), or DDOSIM (Distributed Denial of Service Simulation Tool).
A denial of service attack can be launched from a single machine or from a botnet, which is a network of infected computers that can be controlled remotely by the attacker. The attacker will usually use a botnet to amplify the effects of the attack, by sending a high volume of traffic to the target from multiple sources.
There are a number of ways to defend against a denial of service attack, but the most effective is usually to have a redundant network infrastructure in place, so that if one site or server is taken offline by an attack, traffic can be redirected to another site or server that is still up and running.
