Discover the Ultimate Firewall Management Tool: 7 Essential Features for Unleashing Unrivaled Network Security!
Firewall security management is a combination of monitoring, configuring, and managing your firewall to make sure it runs at its best to effectively ward off network security threats. In this article, we will explore the seven must-have features of a firewall security management tool and introduce Firewall Analyzer, a popular Firewall Management Tool that has set the golden standard in Firewall Management across all vendors of firewall and security products. Furthermore, we'll explain how central firewall policy management, VPN management, log analysis, log retention, compliance management and threat identification/forensics, help create a robust cybersecurity and network security posture that increases your organization's ability to protect its networks, information, and systems from threats.
The seven must-have features of a firewall security management tool are:
- Firewall Policy Management
- VPN Management
- Firewall Change Management
- Compliance Management
- Log Analysis & Threat Identification
- Log Retention & Forensics
- Network Security Alerts
Let’s take a look at each of these features and provide examples that showcase their importance.
Firewall Policy Management
This is the process of managing and organizing your firewall rules. These firewall rules and policies dictate the traffic that is entering and exiting your network, and can also be used to block illegitimate traffic.
Why is this important? Effective firewall policy management can be used to ensure firewall policies never become outdated, redundant, or misconfigured, leaving the network open to attacks.
One of the primary challenges in firewall policy management is the potential for human error. Configuring firewall rules and policies requires a deep understanding of network architecture, application requirements, and security best practices. Unfortunately, even experienced IT professionals can make mistakes due to various factors, such as time constraints, lack of communication, or a misunderstanding of the network's specific needs.
Different individuals within an organization may also have different levels of expertise and understanding when it comes to firewall policies. This diversity in knowledge and experience can lead to inconsistencies, redundant rules, or conflicting configurations, compromising the firewall's overall effectiveness.
Taking proactive steps to manage firewall policies effectively can significantly enhance an organization's security posture and protect valuable assets from potential breaches and cyberattacks. This is where solutions such as Firewall Analyzer can undertake the burden of managing firewall policies through an intuitive, simplified and easy-to-follow interface no matter the vendor of firewall you’re dealing with.
Few of the key-features offered by Firewall Analyzer include:
- Gain enhanced visibility on all the rules in your firewall and a comprehensive understanding of your security posture.
- Quickly identify and record anomalies in redundant, generalized, correlated, shadowed, or grouped rules.
- Analyze firewall policies and get suggestions on changes to rule order to optimize performance.
- Simplify the rule creation, modification, and deletion process.
- Check the impact of a new rule on the existing rule set.

We’ve included all necessary screenshots and easy to follow instructions that will ensure an enjoyable learning experience for both beginners and advanced IT professionals.
This article explains how to detect a SYN Flood Attack using an advanced protocol analyser like Colasoft Capsa. We’ll show you how to identify and inspect abnormal traffic spikes, drill into captured packets and identify evidence of flood attacks. Furthermore we’ll configure Colasoft Capsa to automatically detect SYN Flood Attacks and send automated alert notifications .
Brute-force attacks are commonly known attack methods by which hackers try to get access to restricted accounts and data using an exhaustive list/database of usernames and passwords. Brute-force attacks can be used, in theory, against almost any encrypted data.
Colasoft Unified Performance Management (UPM) is a business-oriented network performance management system, which analyzes network performance, quality, fault, and security issues based on business. By providing visual analysis of business performances, Colasoft UPM helps users promote business-oriented proactive network operational capability, ensure the stable running of businesses, and enhance troubleshooting efficiency.
Peer-to-Peer file sharing traffic has become a very large problem for many organizations as users engage in illegal (most times) file sharing processes that not only consumes valuable bandwidth, but also places the organization in danger as high-risk connections are made from the Internet to the internal network and malware, pirated or copyrighted material or pornography is downloaded into the organization’s systems. The fact is that torrent traffic is responsible for over 29% of US Internet's traffic in North America, indicating how big the problem is.
Troubleshooting network problems can be a very difficult and challenging task. While most IT engineers use a network analyzer to help solve network problems, when analyzing hundreds or thousands of packets, it can become very hard to locate and further research conversations between hosts. Colasoft’s Capsa v8 now introduces a new feature that allows us to highlight-colorize relevant IP conversations in the network based on their MAC address, IP Addresses, TCP or UDP conversations.

Troubleshooting network problems can be a very intensive and challenging process. Intermittent network problems are even more difficult to troubleshoot as the problem occurs at random times with a random duration, making it very hard to capture the necessary information, perform troubleshooting, identify and resolve the network problem.
When working with medium to large scale networks, IT departments are often faced dealing with network loops and

Recent and continuous website security breaches on large organizations, federal government agencies, banks and thousands of companies world-wide, has once again verified the importance of website and web application security to prevent hackers from gaining access to sensitive data while keeping corporate websites as safe as possible. Though many encounter a lot of problems when it comes to web application security; it is a pretty heavy filed to dig into.
Without web hosting services most websites would not exist. The most popular methods to host web applications are:regular hosting, where your web application is hosted on a dedicated server that is intended for your website only, and shared hosting, where you share a web server with other users who will in turn run their own web application on the same server.
Most successful attacks against web applications are due to insecure code and not the underlying platform itself. Case in point, 
When using software that has been developed by a third party, the best way to ensure that the code is secure would be to apply the latest updates. A simple web application will make use of numerous components that can lead to successful attacks if left unpatched. For example, both PHP and MySQL were vulnerable to exploits at a point in time but were later patched, and a default Linux webserver installation will include multiple services all of which need to be updated regularly to avoid vulnerable builds of software being exploited.
While updating software will ensure that no known vulnerabilities are present on your system, there may still be entry points where an attacker can access your system that have been missed in our previous tips. This is where firewalls come into play. A firewall is necessary as it will limit traffic depending on your configuration and can also be found on most operating systems by default.
No amount of code reviews and updates can ensure that the end product is not vulnerable and cannot be exploited. Code reviews are limited since the executed code is not being analysed, which is why web vulnerability scanning is essential. Web scanners will view the web application as a black box, where they will be analysing the finished product, which is not possible with white box scanning or code reviews. Meanwhile, some scanners will also provide you with the option to perform grey box scanning, by combining website scans and a backend agent that can analyse code.
It is imperative to know if your web application has been subjected to an attack. Monitoring the web application, and the server hosting it, would be the best way to ensure that even if an attacker gets past your defence systems, at least you will know how, when and from where it happened. There may be cases when a website is brought offline due to an attack and the owner would not even know about the incident but will find out after precious time has passed.
Monitoring, Auditing and obtaining Security Alerts for websites and blogs based on popular CMS systems such as WordPress, has become a necessity. Bugs, security exploits and security holes are being continuously discovered for every WordPress version making monitoring and auditing a high security priority. In addition, multi-user environments are often used for large WordPress websites, making it equally important to monitor WordPress user activity.
SQL Injections have been keeping security experts busy for over a decade now as they continue to be one of the most common type of attacks against webservers, websites and web application servers. In this article, we explain what a SQL injection is, show you SQL injection examples and analyse how these type of attacks manage to exploit web applications and webservers, providing hackers access to sensitive data.
A few weeks back Security Weekly interviewed Ferruh Mavituna, Netsparker’s CEO and Product Architect. Security Weekly is a popular podcast that provides free content within the subject matter of IT security news, vulnerabilities, hacking, and research and frequently interviews industry leaders such as John Mcafee, Jack Daniel and Bruce Schneier.
8th of May 2015, Netsparker annouced yesterday the discovery of critical security vulnerability contained an HTML file found on many WordPress themes, including WordPress.org hosted websites. As reported by Netsparker the specific HTML file is vulnerable to cross-site scripting attacks and session hijack. WordPress.org has already issued an official annoucement and patch (v4.2.2) and recommends WordPress administrators update their website files and themes.
In the world of information security there exist many tools, from small open source products to full appliances to secure a system, a network, or an entire corporate infrastructure. Of course, everyone is familiar with the concept of a firewall – even movies like Swordfish and TV shows like NCIS have so very perfectly described, in riveting detail, what a firewall is. But there are other, perhaps less sexy utilities in a security paradigm.
Many websites and web applications are like a human fingerprints, with no two being alike. Of course, many websites may use a common backend engine – Wordpress, an MVC framework like Laravel or Ruby on Rails, etc. – but the layers on top of those engines, such as plugins or custom coded additions, are often a quite unique collection. 
Have you ever tried to make a list of all the attack surfaces you need to secure on your networks and web farms? Try to do it and there will be one thing that will stand out; keeping websites and web applications secure. We have firewalls, IDS and IPS systems that inspect every packet that reaches our servers and are able to drop it should it be flagged as malicious, but what about web applications?
Many automated security tools exist not to test and find security holes, but to exploit them when found. Black-hat hackers intent on disrupting your web application possess automated suites as well, because they too, know a manual approach is a waste of time (that is, until they find a useful exploit, and by then it’s sometimes too late).
Netsparker use open source web applications such as Twiki for a total different purpose than what they were intended for. They used them to test their own web application security scanners.
Long gone are the days where a simple port scan on a company’s webserver or website was considered enough to identify security issues and exploits that needed to be patched. With all the recent attacks on websites and webservers which caused millions of dollars in damage, we thought it would be a great idea to analyze the implications vulnerable webservers and websites have for companies, while providing useful information to help IT Departments, security engineers and application developers proactively avoid unwanted situations.
In late February – early March 2014, the eBay database that held customer names, encrypted passwords, email addresses, physical addresses, phone numbers, dates of birth and other personal information, was compromised, exposing sensitive information to hackers. [Source: bgr.com website]
In June 2014, JPMorgan Chase bank was hit badly and had sensitive personal and financial data exposed for over 80 million accounts. The hackers appeared to obtain a list of the applications and programs that run on the company’s computers and then crosschecked them with known vulnerabilities for each program and web application in order to find an entry point back into the bank’s systems.
In February 2014, the Forbes.com website was succumbed to an attack that leaked over 1 million user accounts that contained email addresses, passwords and more. The Forbes.com Wordpress-based backend site was defaced with a number of news posts. [Source: cnet.com website]
In January 2014, Snapchat’s popular website had over 4.6 million usernames and phone numbers exposed due to a brute force enumeration attack against their Snapchat API. The information was publicly posted on several other sites, creating a major security concern for Snapchat and its users.
In 2013 a massive underground attack was uncovered, revealing that over 160 million credit and debit cards were stolen during the past seven years. Five Russians and Ukrainians used advanced hacking techniques to steal the information during these years. Attackers targeted over 800,000 bank accounts and penetrated servers used by the Nasdaq stock exchange.
In 2010, a major security breach on AT&T’s website compromised over 114,000 customer accounts, revealing names, email addresses and other information. AT&T acknowledged the attack on its webservers and commented that the risk was limited to the subscriber’s email address. 
In 2013, during the period 27th of November and 15th of December more than 98 million credit and debit card accounts were stolen from 1,787 Target stores across the United States. Hackers managed to install malware on Target’s computer systems to capture customers cards and then installed an exfiltration malware to move stolen credit card numbers to staging points around the United States in order to cover their tracks. The information was then moved to the hackers computers located in Russia.

In June 2014, Evernote and Feedly, working largely in tandem, went down with a DDoS attack within two days of each other. Evernote recovered the same day, but Feedly had to suffer more. Although there were two more DDoS attacks on Feedly that caused it to lose business for another two days, normalcy was finally restored. According to the CEO of Feedly, they refused to give in to the demands of ransom in exchange for ending the attack and were successful in neutralizing the threat.
Domino's Pizza had over 600,000 Belgian and French customer records stolen by the hacking group Rex Mundi. The attackers demanded $40,000 from the fast food chain in exchange for not publishing the data online. It is not clear whether Domino's complied with the ransom demands. However, they reassured their customers that although the attackers did have their names, addresses and phone numbers, they however, were unsuccessful in stealing their financial and banking information. The Twitter account of the hacking group was suspended, and they never released the information.
Companies and users around the world are struggling to keep their network environments safe from malicious attacks and hijacking attempts by leveraging services provided by high-end firewalls, Intrusion Detection Systems (IDS), antivirus software and other means. While these appliances can mitigate attacks and hacking attempts, we often see the whole security infrastructure failing because of attacks initiated from the inside, effectively by-passing all protection offered by these systems.
Cybercriminals are now focusing their attention on small and mid-sized businesses because they are typically easier targets than large, multinational corporations.
This is the age of networks. Long ago, they said, ‘the mainframe is the computer’. Then it changed to ‘the PC is the computer’. That was followed by ‘the network is the computer’. Our world has been shrunk, enlightened and speeded up by this globe encapsulating mesh of interconnectivity. Isolation is a thing of the past. Now my phone brings up my entire music collection residing on my home computer. My car navigates around the city, avoiding traffic in real time. We have started living in intelligent homes where we can control objects within it remotely.
secure documents were stolen. This resulted in an internal cyber man-hunt. The bait was laid and all further intrusions were monitored. A team of 50 Federal Agents finally tracked down 2 hackers who were using US based social networking systems to hack into the Airforce Base. But it was later revealed that the scope of intrusion was not just limited to the base itself: they had infiltrated a much bigger military organisation. The perpetrators were hackers with the aliases of ‘datastreamcowboy’ and ‘kuji’.
2005: Miami, Florida. A Miami hacker made history in cyber theft. Alberto Gonzales would drive around Miami streets looking for unsecured wireless networks. He hooked onto the unsecure wireless network of a retailer, used it to reach the retailer’s headquarters and stole credit card numbers from its databases. He then sold these card details to Eastern European cyber criminals. In the first year, he stole 11.2 million card details. By the end of the second year he had stolen about 90 million card details.

The screenshot above gives you an idea of what the Server Administration page looks like, which is the first page that would open up once the user has logged in. This is the System Information page. On the left pane you will find several other pages to look at i.e. Basic Settings which displays default port info and HDD info of the host machine, User Account (name says it all), and Audit Log (which will basically show the audit trail of user activity.) 
The Internet connection is vital for many Small to Medium or Large-sized enterprises, but it can also be one of the biggest headaches. How can you know who is doing what? How can you enforce a usage policy? And how can you protect your organisation against internet-borne threats? Larger companies tend to have sophisticated firewalls and border protection devices, but how do you protect yourself when your budget won’t run to such hardware? This is precisely the niche GFI has addressed with GFI WebMonitor.
Many of the displays are clickable allowing you to easily drill down into the data, and if you hover the mouse you’ll get handy pop-up explanations. We were able to go from the overview to the detailed activities of an individual user with just a few clicks. A user here is a single source IP, in other words a particular PC rather that the person using it. Ideally we would have liked the product to query the Active Directory domain controller and nail down the actual logged-on user but to be honest given the reasonable price and the product’s undoubted usefulness we’re not going to quibble.

Ensuring users follow company policies when accessing the internet has become a real challenge for businesses and IT staff. The legal implications for businesses not taking measures to enforce acceptable user policies (where possible) can become very complicated and businesses can, in fact, be held liable for damages caused by their users or guests.
For every business, established or emerging, the Internet is an essential tool which has proved to be indispensable. The usefulness of the internet can be counteracted by abuse of it, by a business’s employees or guests. Activities such as downloading or sharing illegal content, visiting high risk websites and accessing malicious content are serious security risks for any business.
In this era of constantly pushing for more productivity and greater efficiency, it is essential that every resource devoted to web access within a business is utilised for business benefit. Unless the company concerned is in the business of gaming or social media, etc. it is unwise to use resources like internet/web access, and the infrastructure supporting it, for a purpose other than business. Like they say, “Nothing personal, just business”
In our previous article we analysed the risks and implications involved for businesses when there are no security or restriction policies and systems in place to stop users distributing illegal content (torrents). We also spoke about unauthorized access to company systems, sharing sensitive company information and more. This article talks about how specialized systems such as WebMonitor are capable of helping businesses stop torrent applications accessing the internet, control the websites users access, block remote control software (Teamviewer, Remote Desktop, Ammy Admin etc) and put a stop to users wasting bandwidth, time and company money while at work.
Senior IT Managers, engineers and administrators surely remember the days where controlling TCP/UDP ports at the Firewall level was enough to block or provide applications access to the internet. For some years now, this is no longer a valid way of application control, as most ‘unwanted’ applications can smartly use common ports such as HTTP (80) or HTTPS (443) to circumvent security policies, passing inspection and freely accessing the internet.
Apart from the imminent security risk, users who have uncontrollable access are also wasting bandwidth – that’s bandwidth the organization is paying for - and are likely to slow down the internet for the rest who are legitimately trying to get work done. In cases where VPNs are running over the same lines then VPN users, remote branches and mobile users are most likely to experience slow connection speeds when accessing the organization’s resources over the internet.
One of the largest problems faced by organizations of any size is effectively controlling user internet access (from laptops, mobile devices, workstations etc), minimizing the security threats for the organization (ransomware – data loss prevention), user copyright infringement (torrent downloading/sharing movies, games, music etc) and discover where valuable WAN-Internet bandwidth is being wasted.
Most Businesses are completely unaware of how serious these matters are and the risks they are taking while dealing with other ‘more important’ matters.
While illegal downloading is one major threat for businesses, stopping users sharing company data and sensitive information (aka Data Loss Prevention or DLP) is another big problem.
In late 2015, popular Ammy Admin – a remote control software, was 
Figure 2. GFI LanGuard custom software deployment using a parameter for silent installation
GFI LanGuard Agents are designed to be deployed on local (network) or remote servers and workstations. Once installed, the GFI LanGuard Agents can then be configured via LanGuard’s main server console, giving the administrator full control as to when the Agents will scan the host they are installed on, and communicate their status to the GFI LanGuard server.
This article shows how any IT Administrator, network engineer or security auditor can quickly scan a network using GFI’s LanGuard and identify the different systems such as Windows, Linux, Android etc. More importantly, we’ll show how to uncover vulnerable, unpatched or high-risk Windows systems including Windows Server 2003, Windows Server 2008, Windows Server 2012 R2, Domain Controllers, Linux Servers such as RedHat Enterprise, CentOS, Ubuntu, Debian, openSuse, Fedora, any type of Windows workstation (XP, Vista, 7, 8, 8.1,10) and Apple OS X.
