Network Security Tools

The importance of data in business growth is imperative; however, network holds equal importance as it facilitates the flow of data. This makes it important to secure the organizational network to protect data as well as secure network endpoints. Thus, organizations need to implement effective network security and network visibility strategy.

Here is a list of network security tools that can help organizations in securing their network against security attacks:

  • Access Control: The best way to control damage caused by threat actors is to keep them out of the network. In addition to limiting the access of outside threats, it is equally important to take care of insider threats. Access control tools help organizations in keeping out threat actors and limiting user access to network areas that directly apply to user’s responsibilities.
  • Anti-Malware Software: Malware including virus, trojans, worms, keyloggers, spyware, etc. are designed to spread across computer systems and infect an organization’s network. Anti-malware tools assist organizations in identifying, controlling and resolving malware infections to minimize the damage caused to network.
  • Anomaly Detection: In order to detect anomalies in a network, it is first important to understand usual operations of the network. Network security tools such as Anomaly Detection Engines (ADE) allow organizations in analyzing a network, so that when and if any anomaly or network breach occurs, the IT team will be alerted quickly enough to limit the damage.
  • Application Security: Most cyber attackers consider applications to be a defensive vulnerability that can be exploited to cause network disruptions. Including application security tools can help organizations in establishing security parameters for applications.
  • Data Loss Prevention (DLP): Threat actors tend to use humans to cause data breach or network security breach. DLP technologies and policies help in protecting the employees and other users from misusing or possibly compromising sensitive data or allowing data flow out of the network at any of the endpoints.
  • Email Security: Email security tools are another set of network security tools that help organizations in minimizing human-related security weaknesses. Hackers or cyber criminals persuade employees to share sensitive information or inadvertently download malware into targeted network via phishing strategies. Email security tools assist organizations in identifying dangerous emails and blocking attacks.
  • Endpoint Security: Bring Your Own Device (BYOD) culture has become highly integrated in organizations to an extent that it has become tough to distinguish between personal and business devices. Cyber attackers take this as an opportunity and attack personal devices to launch a network security attack. Endpoint security tools add a layer of defense between remote devices and business networks.

Why Organizations Need Intent-Based Networking?

Intent-based networking or IBN applies deep intelligence and intended state insights to networking. These insights replace the need to manually configure the network. In general terms, the administrators can send a request with desired outcomes or intent to the network instead of coding individual tasks manually. The network’s software understands the intent and decides on the steps that need to be taken based on AI and Machine Learning.

IBN has some advantages over traditional and software-based networking which makes it an ideal choice for organizations. Following are some reasons why organizations need IBN:

Reduction In Manual Tasks: In the case of traditional networking, the administrator has to manually reconfigure every task with changing business needs. However, in the case of IBN, the administrator feeds the business needs to the network and the network analyzes these needs, verifies if a change in configuration will solve the need, suggests configuration options, and makes the required changes.

Faster Troubleshooting And Resolution: An intent-based networking system keeps on monitoring itself regularly. This helps in identifying any issues as soon as they arise. Also, IBN has the capability to repair itself without any human intervention using Machine Learning to find suitable solutions.

Reduced Risk Of Non-Compliance: Since the intent-based network is constantly monitoring and repairing itself, it ensures that the system is always in compliance with any policies set by the administrator.

Better Security: Looking for security threats is a part of regular monitoring conducted by an intent-based network. It monitors encrypted traffic as well to be aware of any possible threat. This results in immediate identification and containment of any security breaches to ensure data and network security of the organization.

Optimized Analytics: Understanding network performance is essential for making efficient decisions and predicting network outcomes for minimal risk. IBN regularly collects data about itself which can be used to deduce important information about network performance.

Rapid Implementation Of Business Goals Into Network Configurations: The main advantage of using intent-based networking is that it readily modifies the network configuration as per high-level business goals. The administrator can easily choose from vetted configuration options suggested by IBN saving the time needed for manual planning, testing, and configuration. Faster implementation of business goals into network configuration results in higher ROI.

Most Common Network Problems

With number of devices increasing in home/ offices, network issues are becoming more complex than ever before. Different software platforms and new IoT devices have made computer network rely on several different variables. Even a small issue can disrupt complete network and can cause substantial downtime in the work process.

To solve a network issue, it is first important to understand the network problem and why it arises in the first place. Here we have listed certain common network problems which you must know about.

  • Slow Internet – The most basic problem that your employees might complain about is slow internet which can create a lag while working. There may be a number of reasons behind it. The probable causes are –
    • Too many devices connected on a single network.
    • Some app might be consuming a significant portion of your total bandwidth.
    • Service delays on the part of internet provider.
  • No Connectivity – You might also witness a situation when the wireless network shows the signal but does not connect. This is because either your device is out of the router’s range or there is some problem with the hardware. To correct this, try to place the device close to the router. Also you can replace the network card you are using. Sometimes, updating the network card drivers can be helpful whereas sometimes you might have to change the hardware altogether.
  • IP Conflicts – Every device has an IP address that has access to the network at a given time. However, sometimes two devices might end up having the same IP address due to which the operations of one device may be blocked. In such a situation, the user might not be able to access the protected files and also it can cause a lag for all the connected devices. To avoid this, you must reconfigure your DHCP setup so that the IP conflict is resolved and all the devices on the network get proper access.
  • VOIP Quality Issues – A network stutter can lead to voice call issues such as delays, interruptions and voice quality issues. To curb this problem, install jitter buffers as they create small packets of VOIP information. This will ensure a smooth conversation and help you boost your overall productivity.
  • Inability To Find Network Path – Sometimes an error message displaying network path not found may appear on a user’s screen due to which the device cannot make connection with other devices on the network. Disable local firewalls and also reset TCP/IP to deal with this issue.

Take a note of the above mentioned most common network problems and follow necessary steps to keep them at bay. For more information, call Centex Technologies at (254) 213-4740.

Warning Signs That Your Web Server Is Being Attacked

12th Sep 2017

Web server security should be a priority for any organization, particularly those who deal with sensitive customer data. With advanced hacking concepts such as URL interpretation, session hijacking, HTML injection, SQL injection etcetera, attackers can breach into the network and steal the stored files. In order to identify such attacks, the administrators must monitor their web servers and watch for the following warning signs:

  • General Indications: Most of the hackers try to breach the web servers by attacking the web applications to exploit any loopholes. In order to identify such attacks, you need to keep a check on signs such as multiple ‘404 page not found’ or ‘500 internal server error’ reports in the web server log.
  • Your Website Has Been Blacklisted: If your web server has been attacked and is sending out spam, there is a good chance that it has been blacklisted in search engines and email lists. The visitors on your website may get a message that the site cannot load. It will also become impossible for the end user to reset passwords as sending a reset password email will not be feasible from your end.
  • The Presence Of Web Shells: Web shells are files through which hackers can easily execute other files on the system. Mostly in the form of text, web shells can be easily masked among other files on the system. It is accompanied by extensions such as cmd.aspx or commandshell.php that gives out a code which can be used by the hacker to gain access to your website.
  • Unexplained Server Activity: Keep a regular check on the website so that you can immediately identify any suspicious activity. For instance, your email server process may show high volume of received emails whereas there may be no active visitors on your site. You could also see a Perl script running on your server even though you don’t use it. This is another sign of unauthorized access to your server.
  • Attack On Administrative Interfaces: Almost all the web applications have an administrative interface which can be targeted by hackers in order to reach your system. Watch out for telltale signs such as repeatedly failed login attempts, changes in the account or modifications in the application configuration. This can help you identify if your servers have been compromised.
