The intrusion prevention implementation process does not include information analysis.

1. Cyber ??attack
A cyber attack is a malicious attempt by an unauthorized third party to damage an IT system. Attacks vary in sophistication and tactics, but every effort to "break into" a system has one of the following goals:
Steal valuable files (personally identifiable information, passwords, financial records, etc.) and threaten data leakage to demand ransom.
Collect valuable data and sell it to the highest bidder (usually on the dark web).
Disable a computer or compromise the victim's network (usually to create a launching point for other attacks or to gain a brief competitive advantage).
Disclosure of trade secrets (such as patents or code). Compromising systems and deleting data in a form of "hacktivism". Steal personal data and commit identity theft (often for the purpose of making unauthorized money transfers).
Successful cyberattacks can have a range of negative impacts, including:
Financial losses (a successful attack costs a company an average of $200,000). Data breach. Permanent data loss or corruption. Loss of user trust. Bad news.
If you lose customer data during an attack, you may face legal fines and lawsuits, both of which are common.
As criminals become more creative and aggressive in their tactics, companies are increasingly investing in security. Recent reports show that 69% of U.S. companies are expanding their cybersecurity budgets by 2022 (more than 85% expect allocated budgets to increase by up to 50%). The current key investment areas are:
Cyber ??insurance (still in its infancy in China). Digital forensics. Incident response. Security awareness training. Understanding the difference between attack vectors and surfaces, these two overlapping security concepts must be firmly understood in order to be reliably prepared for malicious activity.
2. Types of network attacks
Malware-based attacks (ransomware, Trojans, viruses, etc.). Malware is malicious software that damages or steals computer, network or server data. .
The malware must be installed on the target device to activate, after which the malicious script bypasses security measures and does one (or more) of the following: Denies access to critical systems or data. Steal documents. Compromise data integrity. Monitor user activity. The damage may even render the system inoperable. Hijack control of a target device (or multiple systems on the same network).
While some malware exploits system vulnerabilities (such as UPnP questions), these programs often compromise the system through human error, such as when the victim clicks on a dangerous link. Open infected email attachments. Plug in a damaged USB or portable hard drive. Visiting an infected website that runs a drive-by download (unintentionally downloading malicious code onto a visitor's device).
Malware is one of the most common types of cyberattacks and comes in many variations. Let's take a look at all the most prominent ones. Spyware: Spyware is a type of malware that monitors infected devices and sends information to hackers. Most attackers use this tactic to quietly monitor user data and browsing habits.
