zero-day exploits
Zero-day exploits are security vulnerabilities that are unknown to the software developer or manufacturer. These types of exploits can be used by attackers to take advantage of a system before the developer has a chance to patch the security hole.
Zero-day exploits are often discovered by security researchers who then sell the information to interested parties, such as government organizations or criminal gangs. The zero-day market is a shadowy, underground economy where exploits can fetch prices upwards of $1 million.
There have been a number of high-profile zero-day exploits in the past, such as the Heartbleed bug and the Microsoft Word zero-day. These types of exploits can have a major impact on the security of the affected software and the systems that use it.
Zero-day exploits are notoriously difficult to defend against. The best way to protect yourself is to keep your software up to date and to avoid downloading and opening files from untrustworthy sources.Click for source
denial of service attacks
A denial of service attack is a type of cyberattack in which an attacker seeks to make a machine or network resource unavailable to its intended users by temporarily or permanently disrupting services of a host connected to the Internet.
A DoS attack can be carried out using a single Internet-connected device. However, more often, a DoS attack is the result of multiple attacker-controlled computers that all target the same victim. When multiple systems flood a target with communications requests, the target can become overwhelmed and unable to process legitimate requests, effectively denying service to legitimate users.
organizations can take steps to protect themselves from DoS attacks. These steps include identifying and patching vulnerabilities, rate limiting traffic, and implemented network security controls.

DoS attacks can have a significant impact on an organization. They can result in extended downtime, lost productivity, and increased costs. In some cases, DoS attacks can even lead to data loss or theft.
Organizations can take steps to protect themselves from DoS attacks. These steps include identifying and patching vulnerabilities, rate limiting traffic, and implementing network security controls.
Identifying and patching vulnerabilities is an important first step in protecting against DoS attacks. Attackers often exploit known vulnerabilities to launch DoS attacks. By patching these vulnerabilities, organizations can make it more difficult for attackers to carry out successful attacks.
Rate limiting is another effective defense against DoS attacks. By rate limiting traffic, organizations can ensure that legitimate traffic is able to get through while blocking or slowing down attack traffic.
Finally, implementing network security controls can help to protect against DoS attacks. Firewalls, intrusion detection and prevention systems, and load balancers can all help to mitigate the effects of DoS attacks.
