Cybersecurity consists of two terms; "Cyber" means relating to the characteristic of computers, information technology, etc., and "Security" means protection or prevention. Thus, Cybersecurity is the term used to protect the systems connected to the internet, such as hardware, software, and data, from cyber threats. This practice of protecting these devices and especially data is done by individuals and enterprises to prevent unauthorized access for attackers trying to enter into the system. A good cybersecurity strategy adopted by the organization can prevent the systems from malicious attacks and stop further damage to the company and its reputation.
About Cybersecurity Threats
A cybersecurity threat is a malicious attack performed by attackers trying to gain unauthorized access to a system or network to deface the IT assets, company's sensitive data, and other intellectual property. There are different types of cybersecurity threats or attacks, they are:
Malware: Malware is that kind of malicious software in which any kind of file or program is used to harm a system. They may vary as per their severity and ...
... can be in the form of viruses, trojans, worms, spyware, etc.
Ransomware: Ransomware is malicious software used to lock users' system files through any kind of encryption program. Cybercriminals then demand payment to decrypt these system files.
Social Engineering Attack: Social Engineering Attack is the wide range of malicious activities accomplished through human interactions. It uses the psychological mindset of employees, tricks them, and takes away the company's sensitive information.
Phishing: In a Phishing Attack, an attacker sends fraudulent or fake emails from a reputed source to the users to steal sensitive information such as login credentials, credit card, and bank account details. There are various types of phishing attacks like email phishing, spear phishing, whaling, smishing, vishing, and angler phishing.
DNS Attack: DNS Attack is where the attacker takes advantage of the vulnerabilities of the Domain Name System (DNS) and redirects the users to other malicious sites. There are various types of DNS attacks like Domain Hijacking, DNS Flood Attack, Cache Poisoning, DNS Tunneling, and DNS Hijack Attack.
Denial of Service (DoS) and Distributed Denial of Service (DDoS): DoS attack is the attack where the attacker floods the systems, networks, or servers with massive traffic of legitimate requests. In a distributed denial-of-service (DDoS) attack,attackers attempt to disrupt traffic of a normal server, network, or service by overwhelming the target with flooding of internet traffic.
Man-in-the-middle-attack: Man-in-the-middle attack is a type of attack where an attacker intercepts the message from the intended source, modifies that message, and that modified message is then sent to an intended destination. The person from the intended destination thinks that the message is received from the intended source where the content was modified.
Wrap up
Cybersecurity is a challenging field where cybersecurity teams have to keep their eyes peeled 24/7 as they have to continuously monitor the threats in the systems, network, and especially the valuable assets of the organization. Attackers are continuously keeping track of the vulnerabilities of the system and then take advantage of this situation and perform data breaches that are creating huge financial and reputation losses for the IT sector. So, the IT sectors should improve their cybersecurity strategy so as to stop these threats.
