Ethical Hacking
Cyber security measures are associated with managing risks, patching vulnerabilities and improving system resilience. Key research subjects include techniques associated with detecting different network behavior anomalies and malware, and IT questions related to IT security. Since these research subjects mainly concentrate on the physical, syntactic and semantic layers, present research infrastructures are focused on studying … Read more
The other option for running VM software yourself is to use commercial software. Most people automatically think of commercial software as a ‘safe’ option, and it usually constitutes the bulk of installed applications. But commercial software has drawbacks, so consider these points: Commercial software costs real money. You have to buy it, and that requires … Read more
Open Source software is usually developed in an open, collaborative manner. The software is typically free, and users are able to use, change, improve, or share it. However, three considerations about Open Source software don’t bode well for use with VM: Questionable code. Open Source code is developed by the public, and you can’t be … Read more
Software-based solutions enable you to install software for vulnerability management on your internal network and run them yourself. Software can automate many processes for VM. However, having the control over VM software carries the usual price tag of having to manage it (and secure it). You have to successfully operate and maintain everything – in … Read more
The VM solution you select needs to provide the capability to scan for and fix vulnerabilities in a broad range of categories, including: Back Doors and Trojan Horses (bypass authentication systems). Brute force attacks (defies cryptography by systematically trying different keys). CGI (exploits the Common Gateway Interface). Databases. DNS and Bind (exploits Domain Name … Read more
Vulnerability management has evolved from simply running a scanner on an application, computer, or network to detect common weaknesses. Scanning is an essential element of vulnerability management, but VM includes other technologies and workflow that contribute to a bigger picture required for controlling and removing vulnerabilities. The primary objectives of VM are to: Identify … Read more
Vulnerabilities and attacks against Linux are creating business risks in a growing number of organizations — especially e-commerce companies, network and IT/security vendors, and cloud service providers that rely on Linux for many of their systems, including their own products. When Linux systems are hacked, the victim organizations can experience the same side effects as … Read more
I don’t envy IT administrators and information security managers for many reasons but especially when it comes to the bring your own device (BYOD) movement taking place in business today. With BYOD, you have to trust that your users are making good decisions about security, and you have to figure out how to manage each … Read more
It pays to find and fix the low-hanging fruit on your network. That’s where you get the most bang for your buck. The following mobile laptop, phone, and tablet weaknesses should be front and center on your priority list: No encryption Poorly implemented encryption No power-on passwords Easily guessed (or cracked) power-on passwords For other … Read more
Wi-Fi is very susceptible to attack — even more so than wired networks if it’s not configured or deployed properly. Wireless networks have long- standing vulnerabilities that can enable an attacker to bring your network to its knees or allow your sensitive information to be extracted right out of thin air. If your wireless network … Read more
