Cyber security And its types

A cyber security threat is any harmful attack that attempts to gain unauthorized access to data, disrupt digital activities, or damage data. Corporate spies, hacktivists, terrorist groups, hostile nation-states, criminal organizations, lone hackers, and disgruntled employees are all examples of cyber dangers.

Several high-profile cyber attacks have resulted in the exposure of sensitive data in recent years. The 2017 Equifax data breach, for example, exposed the personal information of around 143 million people, including birth dates, addresses, and Social Security numbers. Marriott International revealed in 2018 that hackers gained access to its servers and stole the personal information of around 500 million clients. The failure to develop, test, and retest technical measures such as encryption, authentication, and firewalls facilitated the cyber security threat in both cases.

Cyber attackers can utilize sensitive data to steal information or get access to a person's or company's bank accounts, among other potentially devastating acts, which is why cyber security professionals are so important for keeping private data safe.

7 Types of Cyber Security Threats

1. Viruses and malware

Spyware, ransomware, viruses, and worms are examples of malevolent software. When a user clicks on a malicious link or attachment, malware is activated, and harmful software is installed. According to Cisco, once malware is launched, it can:

Access to critical network components is restricted (ransomware)

Install more potentially hazardous applications.

Obtain information without being detected by sending data from the hard disk (spyware)

Individual parts are disrupted, rendering the system inoperable.

2. The Emotet

Emotet is described as "an advanced, modular banking Trojan that primarily works as a downloader or dropper of other banking Trojans" by the Cybersecurity and Infrastructure Security Agency (CISA). Emotet is still one of the most expensive and devastating malware."

3. Service Disruption

A denial of service (DoS) attack floods a computer or network, preventing it from responding to queries. A distributed DoS (DDoS) attack accomplishes the same goal, except it comes from a computer network. To disrupt the "handshake" procedure and carry out a DoS, cyber criminals frequently deploy a flood assault. Further methods may be utilized, and some cyber criminals take advantage of the period when a network is down to launch other attacks. According to Jeff Melnick of Netwrix, an information technology security software company, a botnet is a sort of DDoS in which millions of devices can be infected with malware and controlled by a hacker. Botnets, sometimes known as zombie systems, are designed to target and overpower a target's processing capabilities. Botnets are dispersed around the globe and difficult to track down.

4. The Person in the Middle

When hackers inject themselves into a two-party transaction, this is known as a man-in-the-middle (MITM) assault. According to Cisco, after blocking communication, they can filter and take data. When a visitor utilizes an unsecured public Wi-Fi network, MITM attacks are common. Attackers create a barrier between the visitor and the network, then use malware to install software and steal data.

5. Scamming

Phishing attacks use a forged communication, such as an email, to persuade the recipient to open it and follow the instructions therein, such as submitting a credit card number. "The purpose is to steal sensitive data such as credit card and login information or to infect the victim's laptop with malware," according to Cisco.

6.SQL Injection

SQL injection is a sort of cyber attack that occurs when malicious code is injected into a SQL server. When a server is infected, it releases data. It's as simple as typing the malicious code into a search field on a susceptible website.

7. Attacks on Passwords

A cyber attacker can gain access to a lot of information with the appropriate password. Data Insider defines social engineering as "a tactic cyber attackers utilize that depends primarily on human connection and frequently entails luring people into breaching basic security standards." Accessing a password database or guessing a password are two further sorts of password attacks.

Advantages of Cyber Security

1.It protects an individual's and an organization's personal and sensitive data from being stolen.

2.The key benefit of employing these excellent cyber-security techniques is that networks can be protected against numerous phony nodes attempting to obtain illegal access to the network.

3.The most essential component is that it improves the system's cyber-security.

4.It reduces the likelihood of computers being hacked, reducing the likelihood of system freezes and failures.

5.It improves the business's overall security measures through the use of a better information structure, resulting in smooth business management activities.

6.It discovers the flaws and weak entities that could enable an attacker in gaining access to the system or server. These vulnerabilities, once identified, can assist teams in securing systems and preventing similar assaults from occurring.

7.It defends the computer against spyware, viruses, malicious codes, trojan horses, worms, and a variety of other harmful programs.
