What is a denial of service attack?

A denial-of-service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or permanently.

There are two general forms of DoS attacks: those that crash services and those that flood services. The most common method of attack is to inundate the target resource with communications requests, such that it can no longer respond to legitimate traffic, or responds so slowly that it becomes effectively unavailable. In a distributed denial-of-service (DDoS) attack, multiple machines are used to carry out the attack.

DoS attacks are often the result of multiple systems flooding the bandwidth or resources of a targeted system. DoS attacks are often perpetrated by attackers seeking revenge or political motivation, as was the case with the 2013 attack on the U.S. financial system. In some cases, multiple systems may be used in an attempt to crash a server or overwhelm its resources so that it becomes unavailable to legitimate traffic.

When a DoS attack occurs, it can result in a significant loss of business for the target company or organization. In addition, it can have a negative impact on the reputation of the company or organization and may result in legal action being taken against the attacker.

The best defense against a DoS attack is to have a plan in place to identify and mitigate the impact of an attack. A plan should include steps to take to identify an attack as it is happening and steps to take to protect and restore critical systems and data. Additionally, companies and organizations should consider implementing security measures to prevent or deter such attacks. Visit Site

What is an SQL injection?

An SQL injection is a code injection technique that exploits a security vulnerability occurring in the database layer of an application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. It is an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another.

SQL injection attacks are very common. In fact, they are so common that the Open Web Application Security Project (OWASP) lists SQL injection as one of the Top 10 Most Critical Web Application Security Risks. SQL injection attacks can have a devastating effect on an application, its data, and even its users.

There are two primary types of SQL injection attacks:

1. In-band SQL Injection: This type of attack uses the same channel for both the attack and the resulting data. attackers typically use this type of attack to steal data from a database.

2. Out-of-band SQL Injection: This type of attack uses a different channel for the attack and the resulting data. Attackers typically use this type of attack to execute system commands on the server.

The first thing to understand about SQL injection attacks is that they are possible because of flawed application design. In particular, SQL injection attacks are possible because of inadequate input validation and poor database design.

Input validation is the process of determining whether the user input is valid. For example, when a user enters their username and password into a login form, the application should validate that the username and password are correctly formatted and that the account exists in the database. If the application does not validate the user input, then it is possible for an attacker to enter malicious input that could exploit a vulnerability in the application.

Poor database design can also lead to SQL injection attacks. For example, if a database stores sensitive information such as credit card numbers or social security numbers, then it is important to ensure that the database is properly designed to prevent unauthorized access to this information. Improperly designed databases are often the target of SQL injection attacks because they can provide attackers with direct access to sensitive data.

SQL injection attacks can have a devastating effect on an application, its data, and even its users. In some cases, SQL injection attacks can lead to the complete compromise of a system.

One of the most famous SQL injection attacks occurred in 2008 against the social networking site MySpace. In this attack, an attacker was able to exploit a vulnerability in the site’s code that allowed him to execute SQL commands against the MySpace database. As a result of the attack, the attacker was able to access sensitive information such as user names, passwords, and email addresses.

The MySpace attack highlights the importance of proper input validation and database design. If the MySpace application had properly validated the user input, then the attacker would not have been able to inject malicious SQL commands into the database. Additionally, if the MySpace database had been properly designed, then the attacker would not have been able to access sensitive information.

SQL injection attacks are very dangerous because they can lead to the compromise of sensitive information. It is important to properly design both the application and the database in order to prevent SQL injection attacks.
