What Is Cyber Security?

Cyber security means protecting a computer system from malicious actors. These malicious actors may pose a threat to your computer and may collect unauthorized information.


Viruses in cyber-security are malicious pieces of software designed to attack your computer. They can damage data, corrupt files, and steal your personal information. They can also be used to display spam messages, political messages, and humorous messages.

The majority of active malware threats are computer worms. These programs can infect other programs and give hackers full control of your computer. They can also disable system functions and steal data. They can be spread through email attachments, infected websites, and USB thumb drives.

Other types of viruses are polymorphic, meaning they change their behavior to avoid detection. They can also modify underlying code to hide their presence. Some viruses are also obfuscated, meaning that they can evade anti-malware programs.

These are generally lifeless, meaning they run in the target system’s memory without writing data to the disk. Infected websites typically launch them.

Another type of virus is a boot sector virus, which infects the master boot record of a hard disk. It is also known as a “rootkit” because it gives hackers full control of the infected computer.

Man-in-the-middle attacks

Detecting Man-in-the-middle attacks can be a challenge. The attackers pretend to be legitimate participants and manipulate the conversation. In some cases, they can steal information and use it for identity theft. They can also hijack the data and use it for fraudulent bank activity.

The best way to prevent a Man-in-the-middle attack is to use end-to-end encryption. All communications should use symmetric cryptography, which ensures that only the intended recipient can receive content. In addition, all communications should use private key/public key schemes, which encrypt the data and ensure that the only person who can decrypt it is the one intended to receive it.

The Equifax mobile app allowed attackers to intercept and steal customer data. This attack went undetected until it was too late. In addition, the company didn’t proactively hunt for communications interception, which triggered a security breach.

In addition to the Equifax app, the mobile banking apps of some high-profile banks were also found to be vulnerable. These apps did not use HTTPS consistently. That was a major vulnerability, which allowed attackers to decrypt traffic that had been encrypted with HTTPS.

SQL injections

Whether you are a web developer or a manager of an organization, you need to be aware of SQL injections. These injections are malicious, and they can lead to serious damage. Luckily, there are steps you can take to protect yourself.

First, you need to understand how a SQL query works. It is a standard way of interacting with a database. It allows you to add new data and delete existing records.

Another useful SQL command is the UNION operator. This operator fuses multiple select statements into a single statement, usually using placeholders to separate the data.

Finally, you can use SQL to delete records in your database. This command will do the job if you are deleting an entire table or just one record.

Several websites and applications use SQL databases to store their data. If a SQL command is not properly sanitized, it can give an attacker access to your system without knowing your password.

The best way to protect your web application is to sanitize all user input. If you’re building a new website, consider using SQL injection tools to minimize the risk of a successful attack.

Bot management

An effective bot management strategy is a must for organizations online. A bot management solution is essential to block malicious bots and avoid economic losses. It is also crucial for the security of web properties.

Bots can be used for DDoS attacks and other malicious cyber attacks. They can wreak havoc on web properties and damage the user experience. They can also be used to scrape content from websites. In addition, they can hog resources and spread spam.

Bots are also used by government agencies, hackers, and criminal outfits. They are also used to steal user credentials and sensitive data. Some bots are even used to launch phishing attacks.

These attacks can cause major damage to companies. They can cause losses of time, money, and intellectual property. Bot-based attacks are a growing problem in the eCommerce sector. During peak hours, online retailing is particularly susceptible to bot attacks.

Bots are made up of algorithms that mimic human behaviors. Some bots are benign and do not do much damage. They can also perform tasks that are beneficial to websites, such as enhancing search engine efficiency.
