Is employee internet usage putting you at risk?

Safe Browsing - How Users Internet Habits are Harming your Corporation.

With phishing and ransomware attacks making headlines in the tech world,  it's important to know what you’re up against and understand your options. Many businesses cover the security basics and implement protection from viruses, spam, and other attacks. However security is often breached internally in the most routine ways  - such as workplace web browsing.  It’s a common misconception that  blocking access to porn and gambling sites in the workplace will  protect users and the network from malware. Although banning these sites in a business setting is recommended it doesn’t mean you’re fully protected. Cisco report that 83 percent of malware comes from hijacked sites. This means you can be “served” malware from websites you trust and use daily.

The Internet in 2017

The Internet is something of a security minefield where it's extremely easy for a regular web user to get into serious trouble.  The most conscientious employee can do everything to protect themselves and still be taken by a malware infected site or a phishing scam.

How many Internet users are there globally?

According to numbers from Internet World Stats, there are approximately 3.7 billion Internet users (June 2016) half of which are from Asia.

 

 

 

 

 

 

 

 

 

 

 

 

The web is growing fast, with mobile devices being used to access social media the fastest growing segment, it  grew by more than 280 million globally from 2015 to 2016.

Most Dangerous Places on the Web - Not all Web Dangers are Created Equal

You might think that the dark web is where malware writers hang out, but in fact they prefer popular sites with loads of traffic and several users to choose from. Of course, pornography sites still pose a problem for businesses that need to defend the network from malware, but attackers go for seemingly benign sites, load malware on them, and avoid the usual filters.

A recent Cisco report showed that common sites that host malware include aviation, chemical, pharmaceutical, agriculture and insurance – none of the sites you’d pinpoint as the usual suspects. These sites are often open for browsing on the private network, so attackers are able to avoid standard filters.

How Do Attacks Work?

Hackers have numerous ways to fool users into downloading malware. One common way is to use PDF files. PDF files can have attached scripts that download malware in the background. Disabling JavaScript on PDF files help, but it’s still not 100% effective.

Adobe Flash is no longer supported, but there are still plenty of ads and other content that still use the plug-in. Flash has a history of being a vector for malware, and it’s not even activated by default anymore by recent versions of more popular browsers. Still, older browsers support it and users can enable it, leaving them vulnerable to Adobe Flash malware attacks.

Java-based servlets run on the local machine, but they have become much more infrequent compared to Flash malware. They still pose a problem should users find a malware infected site and give permission for the application to run on the local machine.

Hackers sometimes get access to the site itself, and this is probably one of the most dangerous attacks. They can insert malware or redirect users to a clone of the official site. Users assume that since they typed the official domain in the browser that the redirect is official. From there, the attacker can phish credentials from the user, steal credit card data, or even convince the user to download malware directly from the site. Even more convincing is that the attack is conditional, so attackers will only redirect the user should they come from a search engine, which means that the owner of the site who types the URL directly in the browser will never see that hacked content.

Legitimate Sites May Be Infecting Your Network!

It’s a common misconception that blocking porn and gambling sites in the office will keep you protected from malware. Although banning these sites is advised, it doesn’t mean you’re in the clear. Since these legitimate sites are often used for business purposes, they can easily be overlooked when monitoring user activity. You might never know that a user is infecting his machine should they download any malware from an aviation site or view ads on an insurance site (as an example).

It’s another reason why you should always monitor traffic and activity on your network. Malware could download to the user’s machine and infect the rest of the network, which has been the cause for some high profile attacks in recent years.

You cannot block legitimate sites from access, but you can monitor user activity for suspicious downloads, suspicious network traffic that comes from a local machine, or possible stolen credentials from suspicious login activity. Don’t get caught with malware infecting your network for months and always monitor network activity even if it’s for seemingly harmless Internet

Other Dangerous Places on the Web?

In this discussion we’re talking about general internet usage at work not people accessing the dark web. The dark web is a general term for more seedy corners of the web, where people live  online anonymously. Usually, these sites are encrypted with mechanisms such as Tor. There are also sites or password-protected forums where cybercriminals trade secrets and stolen credit card numbers, these can also be considered part of the dark web.  We will leave the untangling the dark web discussion for another day.

The most dangerous part of the internet tend to be the most popular.

User Behavior - Users and I.T. Pros Alike Continue to Ignore Untrusted Site Warnings

Educating your users is an important part of your enterprise security strategy.  Users need to be trained how to browse safely to protect their personal date, company data and the network itself.  One of the most effective ways to enable web security is the use of SSL certificates. This is essential for sessions such as online banking, official government sites that deal with your private or financial information. An encrypted connection is ensured when the protocol is HTTPS://. 

This warning means that the identity of the designated site is in question, opening the possibility of a man-in-the-middle (MITM) attack.  Once authenticated to the site, an attacker can capture the user session and even capture cookies.  They can also use JavaScript to perform actions on behalf of the user.  Despite these dangers, many users ignore these warnings.  Even more alarming is the fact IT pros do also.  If you see a warning for an untrusted site, close the browser session.  System Administrators  must ensure that trusted certificates support all browser connections within the network.  There is no reason for anyone to navigate to an untrusted site.

Importance of content filtering

Blocking access to malicious websites is now the primary reason for implementing a web filter; although there are many other benefits that can be gained from filtering the Internet. The benefits of enterprise web filtering software are numerous:

  • Cybersecurity
  • Productivity gains
  • Reducing legal liability
  • Conserving bandwidth.

Web filtering is also one of the most effective ways to neutralize the threat from phishing. Phishing involves sophisticated social engineering techniques to fool end users into visiting malicious websites. If employees can be convinced to reveal sensitive information or download ransomware or malware, cybercriminals can easily bypass even the most sophisticated of cybersecurity defenses.

Organizations in heavily regulated industries such as the U.S. healthcare industry face stiff financial penalties for failing to prevent malware infections. In November 2016, the U.S. Department of Health and Human Services’ Office for Civil Rights fined the University of Massachusetts (Amherst) $650,000 for allowing malware to be introduced onto its network. Enterprise web filtering software prevents end users from visiting websites known to contain malware or exploit kits and blocks botnet activity.

Other Benefits of Web Filtering

Enterprise web filtering software can be used to carefully control the web content that can be accessed by employees. By preventing employees from accessing certain categories of website – dating, gambling, and gaming websites for example – employers can dramatically improve productivity.
Filters can be configured to block webpages by category, URLs, or keywords. Employers may choose to block pornography by category, while restricting access to discriminatory website content using keywords. These controls are important to avoid the development of a hostile working environment, which could result in lawsuits being filed by employees. Many enterprises also choose to block access to websites which hog bandwidth: Video streaming websites such as Netflix and YouTube for example.

What to Look for in a Web Filtering Solution

Blocking of Anonymizers, Proxies, and Port Bypassing

A web filter allows organizations to restrict access to certain types of website content. It is therefore important that acceptable usage policies cannot be bypassed. However, by using proxy servers, port bypass, or anonymizers, users could conceivably bypass an organization’s web filtering controls. To prevent end users from circumventing company AUPs, ensure your chosen solution includes IP and Port bypassing controls and that anonymizers and web proxies can be blocked.

Automatic Software Updates

Patch management takes a lot of IT resources; however, unpatched software can  be exploited by hackers. To ease the burden on the IT department, look for a web filtering solution that includes automatic software updates.

HTTPS Inspection

Cybercriminals are increasingly using secure websites, yet not all web filtering software can inspect the content of websites that have SSL certificates. Many malicious websites use fraudulently obtained SSL certificates. It’s vital to the web filter also inspects these websites. For total protection, ensure a web filtering solution includes HTTPS and SSL inspection.

Time-Based Filtering Controls

Time-based controls can be used to carefully control the website content that can be accessed at certain times of the day. This allows personal Internet use to be managed or restricted during normal working hours.

Block Facebook Messenger

Many organizations prefer not to block access to all social media websites at work, yet would like to block access to Facebook Messenger. With WebTitan, Facebook Messenger can also be blocked without blocking access to Facebook.

Role-Based Web Filtering

It is possible to set different web filtering controls for different individuals – or groups of individuals - in your organization. Look for a solution that offers the ability to easily set privileges based on users’ roles in the organization. Some enterprise web filtering software allow filters to be added for all users or specific user groups. Look for web filter software that can be integrated with Active Directory, NetIQ and LDAP to make this process much less time-consuming.
