It's not been long since the Target security breach took place. This affected a lot of banks and left thousands of customers worried about identity theft. If such a security breach can happen in a well-guarded network, then imagine how vulnerable your computer could be! You can trust your computer to simplify your work, but you cannot trust it to keep your data and confidential information safe. It’s not a safe vault! Your computer can be attacked by anyone at any time; hackers and attacker are always on the lookout for easy prey. Even the smallest gap in the security network is sufficient for a strike.

Experts and people who are well versed with such attacks suggest that one way to keep a check on one’s computer is to have inside-out knowledge of the functioning of the machine. Awareness about all the programs running and an update on applications and firewalls is a must for any user. While you work on safeguarding your computer, you must remember to disconnect the computer from the internet. This is done to ensure that you are the only person working on your computer at that point in time. It is also important to go through the task manager so that you can track all the running applications and programs.
 
After you have realized that you’ve had intruders, you need to take some immediate measures to control the damage. Once you know that an intruder had complete access to your computer, you will then have to work hard to undo the damage.

To start with, you must ensure that the anti-malware and antivirus programs on your computer are up to date. You also need to be sure that the software for virus protection is deactivated. Only after all of this will it be fine to run a scan on the full system.

During the scan you may find some suspicious things. If suspicious objects are found, you should remove them immediately. The point to remember here is that there might be a lot of hidden threats on the computer, therefore it is best to keep a close watch on all downloaded and installed items.

Just like ancient times, changing passwords is still the most effective way to protect against unauthorized access. The one thing you must remember is to remove all malware before resetting the password.

<![CDATA[Ways to Integrate Firewalls with Other Security Tools]]>Mon, 16 Jun 2014 08:28:49 GMThttp://intrusionpreventionsystem.weebly.com/blog/ways-to-integrate-firewalls-with-other-security-tools
When it comes to Next Generation Firewalls (NGFW), additional features can be noticed which was previously limited to security controls. These include exclusive features like intrusion prevention systems, application awareness and control, reputation based malware detection, deep packet inspection, etc. These advanced capabilities have helped to increase the range of security activities that are not found in a traditional firewall.

What are the ways to integrate firewalls?
  • Relocating information to a centralized log management system: Modern organization possesses centralized log and event management servers. Apart from compliance purposes, these systems can be used to keep track of various incidents and responses. Thus, integrating firewalls with such a centralized infrastructure helps to detect and stop various malicious activities.
    The selected set of information can be fed into log management systems. Thus, you need to transfer information that may seem suspicious such as IPS alerts or those which block traffic. By being equipped with Layer 8 identity-based technology, enterprises can have complete visibility into user and network activities.

  • Connecting firewalls to incident tracking systems:
    Incident response teams within an enterprise uses incident tracking systems to manage their workload. Integrating firewalls with such systems offers access to incident specific log entries from a hacker’s computer. It helps to detect and prevent malicious web traffic.
    Deploying such system also helps IT administrators to collate more data related to host activities and treat them as per their risk propositions through careful monitoring. This advanced technology can block any suspicious incidents and alert administrators about the same.

  • Taking advantage of threat information providing external sources:
    Do you want to import threat information from external sources like malicious IP addresses, domains, email IDs, URLs etc.? With the help of NGFs, you can share such information throughout an organization to create security awareness.  

The purpose of Next-Generation Firewall (NGF) is to handle multiple security issues. Thus, integrating them with other security tools within an enterprise helps to enhance their capabilities.

<![CDATA[Antivirus: Avoiding Business losses]]>Wed, 14 May 2014 07:33:37 GMThttp://intrusionpreventionsystem.weebly.com/blog/antivirus-avoiding-business-losses
“All’s fair in love and war”. To survive in an age of cut throat competition is not less than fighting a war. Be it the corporate world or everyday life, the zeal to survive is what keeps us going but at time some people cross all boundaries of decency and do not mind committing anything unethical and illegal. Whether it’s introducing a virus into a competitor’s website or introducing a spy amongst the competitors, unethical practices are quite common. Needless to say, it should be dealt with ruthlessly and anyone resorting to such illegal practice should not expect any sort of leniency. However, it is always better to protect and prevent your network through an effective gateway antivirus.

What is Gateway antivirus?
The gateway antivirus is installed at the application level and provides the users with integrated security, blocking potential malicious software before they reach the network. In simple words, this software will help you in protecting your systems from any malicious threats that appear in a PC, and in turn, the other PC’s connected to it will not be affected.

Other types of antivirus threats:

Cloud Antivirus:
Lightweight software is used in a cloud antivirus system in which the majority of the data analysis is done on the provider’s system. Basically when majority of the files are uploaded, the cloud antivirus sends the files to the network cloud where many antiviruses check the files simultaneously for a better detection. Incompatible antiviruses are used in order to eliminate any possible issue. In case of any threat detection, the files from history are re-scanned to improve the process.

Network Firewall:
Known for preventing access to unknown programs and processes, network firewalls don’t identify or try to remove anything from the system. However, they offer protection from the other networks or computers by limiting the access or activity of that software. Blocking requests or access to certain TCP/IP ports is common.  It is not an alternative for a PC antivirus as it works on a broader case.

Online Scanning:
As the name suggests, online scanning is about some websites that offer free online scanning for the entire computer. Whether it is specific computer parts, local disks, external drive or folders/files etc., they can be checked all at once or separately. It is best to scan the systems periodically if it’s the PC software since they are quite slow at times.  The primary action of any malicious software or malware is to paralyze the antivirus software on the computer.

As per the FBI, major business organizations face losses worth $12 million yearly over virus infections.  It is not simple to recover losses, so one must keep their networks updated with the latest antivirus technology in order to avoid any such situation in the future. With some websites providing a range of antivirus options, it is best to opt for an effective antivirus for your gateway at a single click. It will not only secure your network but also prevent further losses.

<![CDATA[Mailboxes: Business Information in Perils]]>Thu, 24 Apr 2014 08:55:31 GMThttp://intrusionpreventionsystem.weebly.com/blog/mailboxes-business-information-in-perils
The cyber mafias operating across the globe have spawned a satanic network which continuously stalks the business communication of flourishing businesses. Email breach is one of their core specializations and fortes. As we are write this blog, hundreds of mailboxes could have been generated in different places.  This means that millions of mail boxes are under a significant threat from hackers, data losses and malicious data breaches at any given time. Email security is the armor developed as a reactionary response to the cyber threats like malware, viruses, phishing, spam, data losses, DHA, DHOS, etc.

A perfect Email security mechanism should encompass all the systems and processes where the data is present. All the aspects of an email should be carefully segregated and secured carefully with the highest attention to minimal needs. The organizations should be able to preserve all the emails for the future perusal as they could also be used as valid evidence.

Tenacity is another aspect of a robust Email security system. It should be tough enough to withstand the firepower of destructive cyber-attacks. This is possible with a robust hardware, software and ingenious virus scanners.

Sometimes, precious data can also be lost because of the endogenic factors like data theft and data disasters. For such unforeseen situations, the management must segregate the data and analyze the threats associated with it for preparing a tactical strategy. Moreover, the organizations should be ready with an Email security backup plan to retrieve the lost data as we never know when a disaster might strike.

Companies get a punch in their gut when they are penalized by the law enforcement agencies for not complying with the standards of submitting the required data. This makes necessary for the organizations to control the data in such a way that it can be salvaged from any kind of situation.

It is always a David versus Goliath kind of situation between data breaches and Email security, as the hackers remain in a quest to find the weak areas of the foundation to strike. Only trusted professionals should be consulted while taking the Email security solutions. It should exemplify traits such as quality, maneuverability, longevity, tenacity and adaptability.

With the advent and usage of Internet Technology, the business users, institutions, government organizations and other users are facing the following risks:

  • Theft, disclosure and misuse of critical or sensitive internal data
  • Unwanted and unauthorized access to the internal systems
  • Interception, decryption of sensitive and confidential information while in transit
  • Hacking and vandalism of critical systems and applications
  • Legal and social threats

To counter these risks including privacy and data security, all organizations are investing huge amount in data security. There are many solutions available to mitigate these risks, one of them is the firewall.

The firewall is a system that stands between the two or more networks to monitor and control the flow of data/information among them. It analyzes the incoming and outgoing data packets to check the adherence with the preconfigured communication rules. Every bit of data/information that goes out or comes in to the network are closely monitored to identify the potential threats to the security and integrity of the applications, telecommunication and computer systems. It alerts immediately about the compromised system, in case the security is breached or about to get breached.

Firewall enables the following:

  • Monitored and restricted access to the internet from the internal systems
  • Monitors the transferred files to block the infected files before they enter the network
  • Maintains the logs of incoming and outgoing data traffic
  • Enforces cyber law and policies

There are two types of Firewall solutions one can opt for: Hardware Firewall and Software Firewall. Let’s focus more on Hardware Firewall and providing details about the same.

Hardware Firewall has a physical existence like any other hardware. It is a network box that contains the customized hardware and software. It has got plug openings and port where the internal network can be plugged and one end the other end is for the external traffic. Its internal software enables to configure the security rules. The firewall works on the basis of these rules. It keeps the internal computer system and application behind the shield and defends against any possible threat. It is a great solution for the organizations who want a one point security solution for all the systems. They don’t need to install separate firewalls on individual systems.

Hardware firewall provides the following benefits:
  • Enables secured remote access to internet protocol ( IP) numbers, ports and applications
  • Allows to pre-configure the range of IP addresses that would be allowed through firewall
  • Blocks social media sites
  • Logs the activities performed by specific IP addresses or ports.
 To conclude, the firewall is a one point security solution for networks against the potential threats.

<![CDATA[Why do You Need a Hardware Firewall?]]>Sun, 22 Dec 2013 04:40:13 GMThttp://intrusionpreventionsystem.weebly.com/blog/why-do-you-need-a-hardware-firewall
Internet has become essential for businesses of any size, and type. It’s a platform on which plethora of information is shared worldwide. Accessing the internet means you are open to numerous networks, servers and computers. This is an open invitation to virus, worms, spam emails, hackers and thus poses an ultimate security risk to the precious data. The solution is a hardware firewall.

Hardware firewall
A hardware firewall is a special device that is deployed on the periphery of your network. It acts as a first line of defense. It is aligned with your internet connection and network to filter all the inbound and outbound traffic. Hardware firewall protects all the computers in the network rather than offering services to a single machine. It is a device that prevents intrusion attempts into your network.

Features of hardware firewall
  • User authentication: This feature identifies users on the basis of user name instead of IP address. It helps in creating policies and regulations for usage of firewalls and website access.
  • Firewall rules management: It helps in controlling the ports for both incoming and outgoing traffic. On the basis of IP or MAC address, the accessibility with that connection can be defined.
  • Load Balance and Fail-over: It facilitates the use of multiple internet connections. You can categorize the users for a specific internet connection. In any case, if the primary internet connection goes down, the users of that group will automatically be moved to another running connection as a backup.
  • Bandwidth management: This helps in controlling the internet speed. Depending upon the type of work, limit the bandwidth of the users on the network. It increases the bandwidth for faster response time for users who need fast speed and significant space for exchanging data.
  • VPN Support: This feature enables remote connectivity. It is useful for employees who have to travel frequently and for those who handle sensitive data.
  • Web filtering: It helps in blocking specific websites for an organization. Some companies want to block social networking sites, job portals, banking sites, online shopping websites and access to personal emails as well. They can restrict the access of entire staff or a group of people from such websites.
  • Log management: It maintains the log of the websites the users visited, the time spent on the site, and data downloaded. This data is helpful in determining the device performance and browsing pattern of the individuals.

  A small investment in hardware firewall can enable an organization to restrict unauthorized entry, filter information, protected network and high security.
