Is Webex a security risk?

An unauthenticated, remote attacker might exploit a vulnerability in the Cisco WebEx browser extensions supplied by Cisco WebEx Meetings Server and Cisco WebEx Meetings Center to execute arbitrary code on a targeted machine. The problem affects the online browsers Chrome, Firefox, and Internet Explorer for Windows. Users should consider upgrading to the latest version of Cisco WebEx for Chrome, Firefox, or IE.

Is Internet Explorer a security risk?

Researchers have discovered a critical security flaw in Microsoft's famed web browser, Internet Explorer 11. The issue, discovered by security firm Kaspersky, may be used by hackers to execute remote code execution on a target device and gain administrator access. It's the second major security breach found in IE this year.

Here's how it works: If an attacker can convince you to visit a malicious website, they can use this bug to take control of your computer. The problem is that most people who are tricked into visiting malicious sites do not realize that they are helping hackers steal their data. When you visit a site using Internet Explorer, it has permission to copy any images files it thinks are important to display properly. These images may contain malware or spyware that can track what websites you visit or install programs on your machine without your consent.

It's very important that you only download apps from trusted sources. Look for software companies that use strong encryption techniques and secure servers when uploading code. Also, make sure you avoid clicking on links in emails or browsing through social media pages looking for login details or other information that can be used to attack your computer. Finally, use caution while surfing the internet; only download files from known websites and be careful about opening files emailed to you.

Microsoft has already released a patch to fix the vulnerability, but it's possible someone might be able to exploit it before then.

What makes a browser secure?

Browser security is the application of Internet security to web browsers in order to safeguard networked data and computer systems against privacy or virus intrusions. Browser security attacks frequently employ JavaScript, sometimes in conjunction with cross-site scripting (XSS), with a secondary payload utilizing Adobe Flash.

The main goal of browser security is to prevent users from accessing malicious websites that contain viruses or steal people's information such as credit card numbers.

Browsers are not completely secure, but they do provide an adequate level of protection against most threats if they are used properly. Browsers help create a safe environment for users by preventing them from visiting harmful sites and promoting stability by automatically closing loopholes that could lead to malware infection. For example, when you visit a site that uses unsupported technology, such as screen readers or text enlargement programs, your browser will warn you before you go ahead and load it. If you refuse to accept the warning, your browser won't let you access the site.

Browsers also protect users by using security checks when they run programs or open links in new windows. These checks look at where the program is from and who sent it, and if there are any signs of trouble, the user is warned. For example, if a website you're about to visit tries to open a program on your computer without your permission, your browser will stop you from doing so.

Are web applications vulnerable?

A recent study put light on one attack vector that is frequently overlooked: online application vulnerabilities. According to a Positive Technologies survey, 44 percent of online apps are prone to data leakage and security issues. Apparently, developers should not assume that users will only use their apps in a secure manner.

Online applications have similar problems as native mobile apps - they can be attacked via several vectors. For example, an attacker can steal user data by hacking into the developer's account or using social engineering techniques to get a user to reveal their password. The good news is that most attacks against online applications can be prevented by following some basic guidelines.

One must always use strong passwords for every website and application. This includes social media accounts and games. Unfortunately, this is where many people fail - they use the same password for all their accounts, which makes them easy targets for hackers.

Applications should never store any sensitive information like credit cards or login details in clear text files or even encrypted databases. These can easily be accessed by anyone who gains access to these documents.

Data leakage is also a problem for online applications because there are no physical barriers between users and computers, so anything from simple email spoofing to cross-site scripting (XSS) attacks are possible.
