File Sharing and Security

February 28th, 2015

In recent times, file sharing is done frequently on the internal servers, websites or through Instant Messaging service. Due to availability of various services on personal devices like smart phones it has become challenging for the organization to secure the sensitive information. Even unprotected Windows networking shares can be exploited by intruders in an automated way. Companies can follow below guidelines to protect themselves from data breach:

  • Protecting your computer against malicious file sharing tools and websites
  • Domain checking of the website for authenticity and then allowing permission to transfer data
  • Downloading data from trusted sites
  • Save downloads instead of running them from pop up window
  • Checking license agreement and privacy statement before installing any software
  • Avoiding illegal downloads
  • Don’t open mail from unknown sources
  • Don’t share your computer access
  • Regularly update your security software with the patches
  • Check your security on regular basis
  • Don’t open your IM on public list
  • Never send sensitive information or files like credit card numbers, SSN’s etc on IM
  • Secure your IM by contacting security admin regularly
  • Highly social nature of IM helps imposters to get information
  • Beware of sharing your personal as well as company information with strangers

Alertsec strengthens security

Alertsec has created a web based encryption service that radically simplifies deployment and management of PC encryption by using industry leading Check Point Full Disk Encryption (former Pointsec) software.

Organizations, especially corporate giants, have to have an information security policy in place that proves they have taken necessary steps and measures to safeguard the information they gathered. If these policies are not adhered to, the regulators may prosecute.

Alertsec Xpress is used by organizations that have recognized the need to protect their information. Customers range from single-user sole traders and consultants to multinational companies with a large number of offices around the globe. Over 4 million users worldwide use Alertsec Xpress’s Check Point Full Disk Encryption.

Browsers under attack

July 26th, 2014

Hackers have focused their attacks on browsers which ultimately has common theme for benefiting from the end users. As old versions of the Java Runtime Environment (JRE) are typically now blocked in the browser by default, Java applets require explicit activation from users.

Bromium Labs researchers said, “so this attack vector becomes harder and harder to leverage” and “It’s evident that attackers continue to shift focus in between ubiquitous internet facing applications, but there’s a common theme throughout – attacking the end users.” It leaves hackers looking to other popular applications to exploit.

According to the reports by the lab, Microsoft’s IE was one of the most patched and one of the most exploited applications in 2014’s first half, targeted more often than Mozilla’s Firefox, Google Chrome, Java, Adobe Flash, Adobe Reader or Microsoft Office.

The lab also mentioned different techniques used in the attacks which are given below –

  • Zero day techniques in which attackers used Adobe Flash to launch action script virtual machine (ASVM) attacks.
  • Action script spray facilitates the use of return-oriented programming (ROP), which allows attackers to execute malicious code in the presence of security defenses

“This technique leverages the way dense arrays are allocated in memory,” wrote Bromium researchers. “If a vulnerability allows an attacker to control the size of a vector, they could make it as big as the whole memory space and then search for the necessary API calls and ROP gadgets.”

“Traditional heap spray was supposed to deal with early address randomization techniques implemented in various operating systems. Nowadays defenses are much more sophisticated. Malicious code must ‘know’ addresses of crucial libraries and API functions in order to execute,” said Vadim Kotov, Bromium’s senior security researcher. “Actionscript spray provides this ‘knowledge,’ while its ancestor doesn’t even address this issue.”

“Action heap spray — as well as traditional heap spray — is merely an instrument to exploit security vulnerabilities,” Kotov said. “If you want to reduce the probability of being compromised, you need to have reasonable patching policy and invest in protection software.”

Get your personal as well as office laptops encrypted by Alertsec

Unencrypted laptops present a major risk of data loss. 80% of information theft is due to lost or stolen laptops and other equipment. About 50% of network intrusions are performed with credentials gathered from lost or stolen devices. The penalties for a data breach are severe not only in terms of the monetary fines imposed on the organization, but also the potential loss of trust from customers and suppliers. Encryption software greatly enhances the security of your organization’s data as the information is not compromised if a laptop is lost or stolen.

Alertsec Xpress is the full disk encryption service that delivers a mobile data protection system for all information stored on laptops used throughout your organization.

Microsoft to Fix two more flaws in IE

June 3rd, 2013

Microsoft will patch 33 vulnerabilities in 10 bulletins relating to Internet Explorer, with two bulletins rated “critical.”

While few details are given about the security issues, today’s advanced security bulletin outlined flaws in a range of other products, including Microsoft Office, .NET Framework, Microsoft Lync, and Windows Essentials.

Bulletin 1 relates to all versions of Internet Explorer 6 to 10, including Windows 8 and Windows RT devices. A patch will be released to fix issues discovered at two security conferences earlier this year.

Bulletin 2 relates to the recent Internet Explorer 8 zero-day flaw designed to target U.S. government workers. The software giant said it was “working” to have a full patch ready for a critical zero-day flaw for Internet Explorer 8, in which the company issued an emergency out-of-band “Fix It” patches on Thursday.

The other eight bulletins are considered “important.”

The remaining eight patches will address flaws that range from denial-of-service errors that can cause Windows to crash, to remote code execution issues in Microsoft Office and Lync, an elevation of privileges that would allow an attacker to gain additional rights to the affected system, and information disclosure issues relating to Windows Essentials 2011 and 2012.

Included with the security patches, we can expect Microsoft to issue a number of non-security related fixes to its Surface Pro and Surface RT tablets, in line with previous months.

Microsoft has delivered 739 updates for Windows 8 and Windows RT in the nearly seven month period since the two versions were launched in October. These fixes included battery life improvements to additional driver support.

The security fixes will be released on May 14 through the usual update channels, such as Windows and Microsoft Update.

Microsoft is doing its best to enhance data security.
