In the era of digitization, cybersecurity is the core focus of businesses and organizations worldwide. By 2025, the global spending on cyber security will reach a staggering $1.75 trillion.
Organizations are shifting their presence online and storing data to cloud services and servers. However, it doesn’t mean the data is secure; the digitally stored information is a prime target for cyber-criminals and hackers. Only in 2021, 1,291 data breach attempts were made, due to which 281,451,400 people lost valuable data and resources. To curb this, security companies are taking a more serious stance on the development of cybersecurity solutions.
What Is Cybersecurity?
Cybersecurity is the practice of protecting your digital devices (mobile devices, computers, servers, networks). It prevents cyber criminals from manipulating and misusing your data. Additionally, it plays a massive role in a country’s defense by protecting against breaches.
Why Do We Need Cybersecurity?
Almost every organization, individual, and government uses digital assets and online practices for daily operations. Businesses like banks and other financial institutions have massive financial and consumer data. They are an ideal target for hackers to hack accounts and steal user credentials and money.
Medical institutions are also a common target for cybercrimes. Cybercriminals conduct ransomware attacks on hospital computers to threaten people for a ransom. Governments are a constant target of cyberattacks from local and international groups, often to sabotage and espionage. This is why cybersecurity is necessary for every organization to prevent substantial damages.
What are Common Types of Cybersecurity?
Organizations can benefit from different types of cybersecurity solutions. Each kind serves a different purpose; businesses can use different kinds simultaneously.
1) Critical Infrastructure Security
Critical infrastructure security is a cyber security branch that secures your IT assets. IT devices are at a high risk of cyber-attacks; it is critical for organizations to ensure their security.
Critical infrastructure security also protects IT assets related to the Internet of Things (IoT). In organizations, many devices are interconnected, and if one of them is breached, the attacker can access other connected devices conveniently.
2) Cloud Security
Organizations often use cloud-based systems and applications to store data as a digital transformation strategy. Several of them are transferring their infrastructure and working methodology to SaaS and other models. Cloud security prevents hacking attempts to cloud based applications, IP addresses, and online data.
3) Application Security
Often applications are connected to IoT and cloud services, which makes them vulnerable to cyber-attacks and data breaches. Application security is a cybersecurity solution that protects applications against hacking, malware, and unauthorized access.
Hackers look for vulnerabilities in applications to get access to user information and manipulate sensitive data like payment and login details. Application security includes frequent testing to find weaknesses and strengthen its security.
4) Operational Security
Operational security in cybersecurity is the process of planning and protecting your digital assets and data. It limits the control of applications and data by allowing access to a limited number of people.
What are the Most Common Cyberattacks?
Cybersecurity’s purpose is to defend the host from various types of cyberattacks. Each attack is different in nature and requires unique measures.
1) Brute Force Attack
A brute force attack is an attempt to acquire the username and password of the users. It is also known as “credential stuffing.” The attacker uses a combination of passwords and usernames to breach data.
Brute force attacks are successful in case of weak and common passwords. Cybersecurity creates a second layer of defense against brute force attacks by adding a two-factor authentication layer.
2) Phishing Attack
Phishing attacks trick people into getting involved with malicious activities. These attacks include sending malicious links, emails, and messages to individuals and organizations. The victim’s device is breached when they click these links, resulting in data and financial loss.
3) Malware Attack
Cybercriminals use malicious software and tools to infiltrate the victim’s device in malware attacks. Once the attackers have entered the device, they can manipulate data for identity theft or gain access to sensitive information.
A common type of malware attack is “Ransomware attacks.” The attackers access a device or many devices simultaneously. They then put malware on the victim’s device. The software hijacks the device and asks for a ransom from the victim to release the system.
Large organizations often become victims of ransomware attacks because the attackers can infect many devices simultaneously and get substantial financial gains in return.
4) Man In the Middle (MitM) Attack
In man-in-the-middle attacks, the attackers interrupt the communication between two parties. They get access to valuable data through contact between two parties; they can steal and manipulate the data.
Unsecured devices like unprotected Wi-Fi routers or portals can be victims of MitM attacks. So avoid sharing sensitive information like passwords, usernames, and credentials on unsecured channels.
5) SQL Injection
In a SQL injection attack, the attacker uses a web application database by using malicious code to get unauthorized access. The SQL injection manipulates SQL code to access the unprotected data.
What are the Most Effective Cyber-Security Prevention Practices?
Organizations and individuals can use many cybersecurity practices to protect their data and devices. You can invest in the following cyber-security practices to avoid breaches.
1) Anti-Virus Software
Anti-virus software is an effective measure to protect your device and data from malicious links, viruses, and malware attacks. Many anti-viruses give essential protection from threats with the free version, but you can get their advanced protection by purchasing their premium version.
2) Two-Factor Authentication
Two-factor authentication prevents phishing and unauthorized login attempts. If the attacker made a successful login attempt on any platform (social media or web), the two-factor authentication would require a code or confirmation from the account owner. The attacker will not be able to infiltrate, and the victim will be notified.
3) Cyber-Defense Tools
Many platforms are now developing cyber defense tools and software that detect vulnerabilities and cyber threats. Once the threats are detected, these tools can effectively terminate the threat and create effective practices.
Cybersecurity has become significant for organizations and governments around the world. However, cybercriminals are becoming more sophisticated with time, and, fortunately, so is cybersecurity. Cybersecurity is also a promising career; the need for cybersecurity professionals continues to grow as the world evolves, with everything transforming into a digital version.
