What is Java?
Many applications and websites require end-users to have Java installed. Websites incorporate Java applets (small applications) to enhance the usability and functionality of a website. When a user visits one of these websites, depending on their browser's security settings, they may have no idea that the Java applet is automatically running.
End-users typically have "Java Runtime Environment" (JRE) installed on their computer. In many instances, this software was pre-installed on their computer. More recently, this practice is becoming less common. If JRE is not installed on your computer, and you visit a website that requires JRE, generally, you will be prompted to install JRE.
What Depends on Java?
Some campus applications still require a Java JRE.
Risks with Java
Java is designed to work on almost any computer and has been prone to numerous reports of vulnerabilities. According to the SecureList IT Threat Evolution Report released by Kaspersky Lab in May 2013,
The most widespread vulnerabilities are found in Java and [the vulnerabilities] were detected on 45% of all computers.
These attacks are based, at least in part, on older versions of Java. When a newer version of Java is released and installed on a machine, the older version may not automatically be uninstalled. This was intended to provide an easy way to roll back to an older version in case of compatibility issues. Attacks can be used by hackers to leverage and to exploit the vulnerabilities that exist in those versions. This makes Java's weaknesses an attractive target for hackers and cyber criminals.
