Virtualization – Specific Security The Elixir of VM Stall

A few years back in history, organizations were worrying that their virtual machines will have management issues, problems in its performance, security and also its staff. That was because of VM sprawl. Now another problem is haunting them and it is the VM stall.

VM stall has the tendency of putting the converted non-production type low-risk systems to a standstill. The virtualization projects that organizations keep localized or confined in certain areas of the physical network will hit a wall; a wall that they would hit every time they decide to secure each thing they need. At start experts would conduct security tests and pen testing to know what this wall is all about and what could have been done to avoid it. They have found out that this virtual wall could have been avoided if they have deployedvirtualization securities that have the ability to enable dynamic virtualized networks without compromising the security.

VM stall is indeed a problem, but there are available solutions nowadays that can be used in surmounting that wall and erase the fears an worries of losing control on the system or degrading its performance. Continuing the phases in virtualization of an organization will lead to a faster server provisioning as well as management.

It is a stated fact that companies are hesitant when they allow non-administrators or non-pros to conduct certain testing on their systems such as pen test; much more if they allow them to maintain their VMs. There are chances that these systems will be misconfigured or not maintained properly and it could lead to open vulnerabilities to the system.

Solutions that are used implementing VM will enforce other technology that exists today. Furthermore, these solutions will allow organization to mix workloads, turn on the VMotion as well as get better ratios in VM-to-host compressions without the added risk on the VM security. Virtualization-specific security also helps overcome the wall of VM stall and at the same time it mitigates ROI’s arguments.

The practical example of virtualization-specific security’s impact on the ROI is this. If a certain customer has 3 VM hosts as well as 30 VMs; 10 VMs are used for various applications of thehost business while the 20 are for 2nd tiered VMs. If we assume that the max capacity of each of the host is only 20 VMs, the customer shall protect as well as limit the access to the critical VM by using VLANs. For instance, 5 VMs is allotted to 1st host, 5 VMs allotted to the 2nd host and 20 VMs to the 3rd host. Since the 3rd host is maxed out, the customer will need to add additional non-critical VMs, deploy additional hosts since the 1st and 2nd hosts are isolated even if they aren’t maxed out. The logic behind this is that it is possible to achieve security without mixing the workloads and physically isolating the critical VMs to any VLN.  However, this happens at the expense of the ROI – thus there is a stall.

A 2nd example is a customer who used granular security in each VM, the customer can mix the workloads; obtain departmental isolation as well as security without reducing the host’s VMs. Thus the customer can load 10 VMs in every host as well as have headroom for the additional 30 VMs that are spread throughout the existing host. That is the power of servervirtualization-specific security and ROI.

Virtualization security helps the security and the ROI concerns which related to the reticence of the deployment. It is important that the security packages have been evaluated and that they have the needed features to provide granular isolation as well as have the required automated security.

There are some few things needed to consider when searching for the solution. It must have layered defenses like firewalls, AV software, IDS and penetration testing tool kits. It must have vCenter integration to make the solution for the security aware in the changes of the network. VM Introspection that provides X-ray view to know what is installed in each VM. It also must have compliance enforcement to alert or quarantine the VMs that have failed the compliance checks. An auto-VM security that is used for brand new VMs is needed to automatically apply the security policy that is given for each VM type. Finally, VM image enforcement is needed to monitor each of the VM images for the compliance of the right configuration.

Increasing Dangers of Cybercrime

Companies should stop telling themselves that their network security systems are enough against any cyber threats looming in the Internet’s horizon nowadays. In fact, they should stop waiting for these threats to happen in their systems before they take any action against it. The risk of these cyber crimes isn’t a laughing matter and imminent doom is the only thing that awaits irresponsible and reckless companies.

Because of the constant change in our world today, the threats in the network systems of companies are further evolving and it may come from any kind of vector – mobile phones person to person networks, social media, Emails, web applications and so much more. To make matters worse, the security defenses and methods the companies employ like the regular penetration testing and anti virus software is being left behind. The technologies and skills these cyber criminals employ are sometimes far more superior than any other IT experts working as security administrators in different companies.

Due to their superiority when it comes to skill and tools used in hacking, creating sophisticated codes for malware, spear phishing and bot nets, committing cyber crime nowadays is as easy as pie. As a matter of fact, some cyber criminals don’t even need to lift a finger to do a thing; everything he wants to be done will be accomplished by the software he an unwilling victim downloads.

Aside from that, cyber criminals who are expert in writing different sophisticated software used in cyber crimes can even sell their software on a certain price to other criminals who lack the sophistication, skills and knowledge to make their own code. Thus, anyone who wants to hack a certain establishment will be able to use sophisticated software to accomplish everything he needs to be accomplished. The best example of sophisticated malware that is being sold in the Internet nowadays is the ZeuS malware. This dangerous malware is highly sophisticated and can be programmed to do different task depending on the type of attack a ZeuS user may want; ZeuS can also be used in building a much potent threat – bot nets.

Many security experts are getting more and more concerned about the evolution of cyber crime. Furthermore, the integration of these cyber crimes into an organized crime has created a greater scope of threat in many industries today. Criminals in cyber underground can share the sensitive information they have or work together to build a team to take down the tough security systems of some company. It’s an A-team of criminals adept in making codes, decrypting encrypted files, intelligence gathering deploying malware and scanning company systems for vulnerabilities they can exploit.

Nowadays, cybercrime has become a profession to some individuals and the levels of professionalism they have can be amazing. Potential clients will approach cyber criminals in these underground forums where clients can hire them to initiate attacks to specific targets – of course on a certain price. They will pay these crooks to launch DDoS attacks, steal or destroy sensitive information or others. But before clients hire these crooks, clients would often ask them to show their skills and how good they are in their trade.

Still, not all cyber criminals assemble teams to work together for a single purpose; individual cyber criminals can work on their own because of their bot nets. And what motivates them in making these crimes is the cash they could acquire from different companies like banks and other financial institutions. But some of those criminals aren’t focusing on financial institutions only; why would they hack on banking networks where there are securities that are tough to break or circumvent. They would rather hack the networks of some large scale businesses and institutions like restaurants, universities and hospitals. They can still get the needed information of their target without having to face difficult security systems.

These threats aren’t only used in stealing or making profit from different companies, sometimes these threats are used in attacking different governments. Espionage has become easy because of the Internet; any country could steal important information or make any destabilization plots against the target country.

Indeed, whether it is the government or other private industries, it is important to strengthen their defenses against cybercrimes. They should explore the vulnerabilities of their systems which can be exploited; it is easy to identify the vulnerabilities of network by completing a simple pen test. It can only be done by an expert in network security who has completed penetration testing training.
