Secure Your Business Travel

January 27, 2015

Business travelers are always a prime target for the cyber criminals and spammers to gain access to their computers and confidential data stored therein. Thus, before you go on your next business trip, make sure that you follow these important security tips in order to keep your system safe from any sort of vulnerabilities.

  • Install Proper Security Updates And Patches: Before you leave for your journey, update the security software of the operating system and other applications for your computer. Also update the anti-virus software and if possible, enable it to update automatically. Although these processes may take a while, but it can prevent your system from security attacks by hackers.
  • Download Updates From Authorized Websites: If your computer suggests you to update certain software or applications, do not click on the ‘update’ button straightaway. This can be a malware to install spam software in your operating system. To avoid this, you should go to an authorized website and download the updates directly from there.
  • Always Use Virtual Private Network (VPN): Whenever you use the internet connection offered at public places such as hotels, airports and cafes, there is a higher possibility that your data can be intercepted and accessed unless it is properly encoded. This may include your username, password, documents and emails that you send etc. If your company provides VPN access, make sure you use it while traveling.
  • Beware Of Free Access Points: Unsecured Wi-Fi access points may seem to be tempting, but they may be a trap set by the hackers to spy on your private data. Malicious hotspots can also be used to redirect the users to spam websites that can infect the computer with viruses. However, if you need to connect to the internet, make sure that you opt for Wi-Fi services that require a password for authentication.
  • Encrypt Your Hard Drive: Your laptop may consist of some important business related data which may be at the target of cyber criminals. Make sure that your hard drive is properly encrypted and has a complete backup to keep all your information secure.
  • Avoid Using Public Computers: Computers in internet cafes and hotel business centers should never be trusted for any private communication or transaction. There may be a key logger installed to detect your username and passwords as you type.

It is also advisable that you change your laptop’s password once you have returned from the business trip.

What Is The Internet Of Things?

January 17, 2015

The Internet of Things (IoT) may be described as a network of devices connected to the internet to communicate and share valuable information. The concept entails internet connectivity beyond the traditional devices such as computers, tablets and smart phones to TVs, cars, electronic appliances etc. In a nutshell, every device that has an embedded technology to be able to connect to the internet comes under the category of Internet of Things.

Mainly, it consists of three essential components:

  • The devices themselves
  • The network that connects them to  other devices
  • The systems that can utilize the data shared through the connected devices

With the help of this infrastructure, the IoT can be used to make our lives better in a number of ways by allowing constant connectivity throughout the world, real time tracking of everything etc. However, every new technology comes with its own share of vulnerabilities, and so does the Internet of Things. Ranging from cross-site scripting, weak passwords to SQL injections and Heartbleed, there are a number of security concerns surrounding these devices. Some of them are:

  • Privacy Issues: Most of the IoT devices collect personal information of the user such as name, date of birth, address, bank account, credit card details etc. More disturbing fact is that most of these gadgets still transmit these particulars over the internet without any encryption. Thus, it is highly possible that this data may be misused by the cyber criminals.
  • Insufficient Authentication: There are many users who still rely on weak passwords that are short and easy to remember. A number of devices do not even require a strong password for the user to access the internet. Thus, it provides an easy way for the hackers to decode the password and penetrate the data stored.
  • Web Interface: One of the common security concerns with the Internet of Things is issues in the UI including issue poor session administration, cross-site scripting and weak default authorizations. This allows the hackers to identify user accounts and manipulate them by resetting passwords.
  • Insecure software: While downloading any software updates, most users do not use proper encryption. With such an error, the hackers can easily intercept these downloads and even see or modify them for their own benefit.

Given the above concerns, the manufacturers of IoT devices must take the necessary steps to ensure the user’s security while being connected to the internet.

Cyber Security Concerns In 2015

January 10, 2015

After a year of facing some challenging cyber security threats like Shellshock (Bash Bug) and Heartbleed, experts have started to make predictions for security concerns in 2015. It is believed that besides traditional cybercrimes like data breaches and password attacks, many larger hacking attacks can also be expected this year.

Given here are some of the potential threats predicted by cyber security experts:

  • XSS Attacks: It is difficult to find high-risk vulnerabilities in credible web products, such as SharePoint, WordPress etc., however, low-risk vulnerability like XSS is quite common. As these attacks give the same results as an SQL injection, hackers usually prefer to exploit XSS to access confidential data.
  • Third Party Plugins: Even though the core databases of many web products are quite secure, third party programs are at high risk for security breaches. Any outdated plugin can put the entire application at risk.
  • Chained Third Party Attacks: Reputed websites are usually protected against critical vulnerabilities. Thus, it becomes easy for the hackers to combine several low to medium risk vulnerabilities to gain access to the websites.
  • Ransomware Attacks: This is a type of malware that restricts a user to access the computer that it infects. It even demands certain sum of money to be paid to the hacker after which the restriction can be removed.
  • The Internet of Things: Connecting your gadgets and devices like mobile phones, TVs or cars to the internet will also be a major cyber security concern in 2015. As these devices do not have any sophisticated security applications, it is much easier for the hackers to access important data and manipulate the system.
  • Cyber Espionage: Also known as cyber spying, this is a very common attack used by the hackers to get hold of confidential information illegitimately from a computer system.
  • Point of Sale Attacks: With the introduction of Apple’s virtual payment system Apple Pay, cyber criminals will definitely look to abuse any flaws in the application. In addition, other digital payment systems on mobile phones will also remain the target of hackers.
  • Blastware: This malware destroys operating systems, deletes important information and wipes out the data required to track the hackers. Much like Ransomware, it also enables the cyber criminals to get control over the entire system and manipulate the data for malicious purposes.

Hackers continuously look for insecure and vulnerable networks in order to implement their attacks. Thus, in order to deal with the cyber security concerns in 2015, individuals and organizations must update their security systems regularly.

Things To Check If Your Internet Is Blocked On Your PC

December 30, 2014

You might have witnessed times when you are suddenly unable to connect to the internet from your computer system. This could be due to several reasons which most people are unable to detect. Given here is a complete list of the common things to check when you witness internet connection not working on your PC.

Unplugged Network Cable Or WI-Fi Disabled

This is the most common reason why most people are unable to connect to the internet. The connection failure is not due to a problem in the network, but because of Wi-Fi adapter been shut off in the laptop. In home networks, the router might have been inadvertently unplugged by someone.

Rule Out Fake Alarms

Instead of problem in your network connection, there are chances that a particular website may be down. Hence, before assuming any conclusion, make sure you visit several popular websites rather than just a single one.

Avoid IP Address Clashes

If more than one computer is using the same IP address, the clash between them can also prevent the internet connection from working properly. To resolve this issue, you should renew the IP address of any of the computers having confilct. If your network has a static IP address, you can manually change it to any other number.

Check For Faults in Computer Firewall

Firewalls installed on many computers are intended to restrict unauthorized traffic to affect network processes.  Regrettably, due to an error, these software systems can sometimes also block valid internet users. Also, when more than one firewall is installed on the same computer, conflicts between them can also lead to erroneously block traffic. If you have recently updated or installed a computer firewall system, disable it temporarily to see if it has been causing the problem in internet connection.

Check If Wireless Signal Is In Range

If you are on a Wi-Fi network, the performance of the connection will be influenced by the distance between the wireless access point and computer system. Farther the Wi-Fi device, slower will be the internet speed. Determine the strength of your wireless connection to diagnose the problems in your internet.

Changes In Wireless Network Configuration

Wi-Fi networks usually require matching WEP or WPA security keys to connect. If a person changes the password or encryption key at the access point, all the devices will be unable to connect to internet. You can contact the network administrator to confirm if the pin has been changed recently.

If all the above things are working correctly, contact your internet service provider to check if there is an outage in your area. They can also guide you to troubleshoot the connection problem.
