Understanding Application Security Threats

Hackers and cybercriminals are consistently finding new ways to exploit vulnerabilities in applications and compromise users' private information. With so many applications available, each with their own potential security issues, it's important for organizations to understand the most common threats.

Malware and Phishing
Securing Your Applications software, or malware, remains one of the biggest threats to application security. Malware can be secretly installed on a user's device when they click a link or download a file. Once activated, malware may steal passwords and financial details, block access to systems, or encrypt files until a ransom is paid. Phishing is a common tactic used by cybercriminals to trick users into downloading or installing malware by disguising malicious links as being from a legitimate source. Staying alert and cautious of unsolicited messages can help reduce the risk of falling victim to phishing.

Injection Attacks
Injection attacks occur when untrusted data is sent to an interpreter as part of its command or query. This can tricks the interpreter into executing unintended commands or accessing data without proper authorization. Two common types are SQL injection, which can expose or corrupt database records, and command injection, which may allow an attacker to install programs or view/change data. Carefully validating all user-supplied data can prevent these attacks.

Broken Authentication
Flawed authentication mechanisms in applications open the door for hackers to gain unauthorized access. If credentials like usernames, passwords or session tokens are not properly protected during storage and transmission, they may be stolen. Attackers can then use these stolen credentials to impersonate legitimate users. Implementing multi-factor authentication and securely hashing and salting passwords helps strengthen authentication security.
