denial of service attacks
A denial of service (DoS) attack is an attack in which the attacker seeks to render a computer or other service unavailable to users. This can be accomplished by flooding the target with traffic, or by sending it requests that require a lot of work to process.
DoS attacks are usually launched by a group of computers, which are sometimes called a botnet. The computers in a botnet are typically infected with malware that allows the attacker to control them remotely.
There are two common types of DoS attacks:
1. Volume-based attacks: These attacks flood the target with traffic, causing it to run out of resources and become unavailable. The traffic can come from a single source (e.g., a single computer) or from multiple sources (e.g., a botnet).
2. Protocol-based attacks: These attacks exploit weaknesses in the protocols that govern how computers communicate with each other. By sending malicious requests, the attacker can cause the target to use up its resources and become unavailable.
DoS attacks are a serious problem because they can render critical services unavailable, and they can be very difficult to defend against.
There are a few things that organizations can do to protect themselves from DoS attacks:
1. Use firewalls and intrusion detection/prevention systems: Firewalls can help to stop some types of DoS attacks by filtering traffic and blocking malicious requests. Intrusion detection/prevention systems can also be used to identify and block suspicious traffic.
2. Rate-limit traffic: By rate-limiting traffic, organizations can ensure that legitimate users are not impacted by DoS attacks.
3. Use multiple providers: Organizations can protect themselves from some types of DoS attacks by using multiple providers (e.g., using multiple Internet service providers).
4. Implement security measures: Organizations should implement security measures (e.g., authentication, authorization, and encryption) to make it more difficult for attackers to launch successful DoS attacks. View it
adware
What is adware?
Adware is a type of software thatdownloads and installs itself on a victim’s computer without the user’s knowledge or permission. Adware is often bundled with other free software programs that can be downloaded from the Internet. Once installed, adware can display popup ads, hijack the user’s homepage, or even slow down the computer. Some adware programs are difficult to remove, and may require the use of antispyware or antivirus software.
What are the dangers of adware?
Adware can be annoying and intrusive, but it is generally not considered a serious threat to computer security. However, some adware programs can be used to collect personal information such as email addresses and passwords. In addition, adware-sponsored ads can be used to spread malware, redirect users to phishing websites, or trick users into disclosing personal information.
How can I protect myself from adware?
There are a few simple steps you can take to protect yourself from adware:
Install and update antivirus and antispyware software.
Be cautious when downloading free software from the Internet. Read the End User License Agreement (EULA) carefully and make sure you understand what you are agreeing to. Pay attention to any warnings about installing third-party software.
Do not click on pop-up ads, even if they look legitimate.
If you think your computer is infected with adware, run a scan with your antivirus or antispyware software. If you are unable to remove the adware, you may need to reinstall your operating system.
