It is seemingly a more popular thing today for hunters who are scouting for wild game to find a trail camera that really does provide the most discrete surveillance in a natural setting. All experienced scouts know how extremely necessary it is to not leave behind any scent or give wildlife any cause to suspect there is something out of the norm or awry. Relying upon equipment that will help keep a scout’s presence unknown to the wildlife at the site is the ultimate achievement. Getting the best images of the wild game is equally important and total discretion is valuable in achieving this goal.
Animals are smart. Any unusual sound and a flash can be startling to a deer. The more aged a buck is the wiser he becomes. He learns over the years when the hunting season begins and is able to alert others in the herd if they feel something is amiss. The buck becomes very well trained in detecting unusual sounds and scents. It’s like he acquires a 6th sense when it comes to the environment he lives in. So, this ups the game for hunters when scouting. They need to be cautious and very aware of their entering the woods or specific area for planting a trail camera, so they leave no scent behind.
One way for a hunter becomes more skilled in a stealth-like scouting technique when placing a scout camera in the midst is to find a black-out or no- glow infrared trail camera. This will provide the most concealment as possible, not only during the day, but during the night as well.
Trail camera manufacturers have put out an excellent selection of black-out or no-glow infrared cameras on the market. The technology of these cameras seem to improve every year. The black-out trail cameras provide infrared LED lights, which aide in achieving better illumination of images during the night and without a visible flash to animals and humans alike. This is achieved by way of special filters covering the infrared LED light box. These are very beneficial and can provide the hunter with fantastic results in the field. Read the rest of this entry »
Why use FIM in the first place?
For most people, the answer is ‘because my auditor/bank/security consultant said we had to!’ Security standards like the PCI DSS mandate a requirement for regular file integrity checks, including log file backups/archives, and this is the initial driver for most organizations to implement FIM.
Unlike anti-virus and firewalling technology, FIM is not yet seen as a mainstream security requirement. In some respects, FIM is similar to data encryption, in that both are undeniably valuable security safeguards to implement, but both are used sparingly, reserved for niche or specialized security requirements.
How does FIM help with data security?
At a basic level, File Integrity Monitoring will verify that important system files and configuration files have not changed, in other words, the files’ integrity has been maintained.
Why is this important? In the case of system files – program, application or operating system files – these should only change when an update, patch or upgrade is implemented. At other times, the files should never change.
Most security breaches involving theft of data from a system will either use a keylogger to capture data being entered into a PC (the theft then perpetrated via a subsequent impersonated access), or some kind of data transfer conduit program, used to siphon off information from a server. In all cases, there has to be some form of malware implanted onto the system, generally operating as a Trojan i.e. the malware impersonates a legitimate system file so it can be executed and provided with access privileges to system data.
In these instances, a file integrity check will detect the Trojans existence, and given that zero day threats or targeted APT (advanced persistent threat) attacks will evade anti-virus measures, FIM comes into its own as a must-have security defense measure. To give the necessary peace of mind that a file has remained unchanged, the file attributes governing security and permissions, as well as the file length and cryptographic hash value must all be tracked.
Similarly, for configuration files, computer configuration settings that restrict access to the host, or restrict privileges for users of the host must also be maintained. For example, a new user account provisioned for the host and given admin or root privileges is an obvious potential vector for data theft – the account can be used to access host data directly, or to install malware that will provide access to confidential data.
File Integrity Monitoring and Configuration Hardening
Which brings us to the subject of configuration hardening. Hardening a configuration is intended to counteract the wide range of potential threats to a host and there are best practice guides available for all versions of Solaris, Ubuntu, RedHat, Windows and most network devices. Known security vulnerabilities are mitigated by employing a fundamentally secure configuration set-up for the host.
For example, a key basic for securing a host is via a strong password policy. For a Solaris, Ubuntu or other Linux host, this is implemented by editing the /etc/login.defs file or similar, whereas a Windows host will require the necessary settings to be defined within the Local or Group Security Policy. In either case, the configuration settings exist as a file that can be analyzed and the integrity verified for consistency (even if, in the Windows case, this file may be a registry value or the output of a command line program).
Therefore file integrity monitoring ensures a server or network device remains secure in two key dimensions: protected from Trojans or other system file changes, and maintained in a securely defended or hardened state.
File integrity assured – but is it the right file to begin with?
But is it enough to just use FIM to ensure system and configuration files remain unchanged? By doing so, there is a guarantee that the system being monitored remains in its original state, but there is a risk of perpetuating a bad configuration, a classic case of ‘junk in, junk out’ computing. In other words, if the system was built using an impure source – the recent Citadel keylogger scam is estimated to have netted over $500M in funds stolen from bank accounts where PCs were set-up using pirated Windows Operating System DVDs, each one with keylogger malware included free of charge.
In the corporate world, OS images, patches and updates are typically downloaded directly from the manufacturer website, therefore providing a reliable and original source. However, the configuration settings required to fully harden the host will always need to be applied and in this instance, file integrity monitoring technology can provide a further and invaluable function.

In case you have decided to buy a tablet computer, the next thing you should perform is actually to discover the one that’s ideal for you. Nevertheless, it could be a tough task for you to obtain the one that’s ideal for you as there are a lot of good options available. Here are several points to search for in a tablet which would assist you to identify the best rated tablets for your needs.
The initial point you need to look for when buying a tablet computer is the Operating System (OS). It is very crucial to inspect it due to the fact that it represents the experience you will have when you interact with your tablet computer. The two most prevalent operating system at the moment are definitely Apple iOS and Google Android. Choosing between Apple IOS and Google Android should depend merely on your own tastes and how you like it as there is no specific operating system which might be called “the best” overall. Apple IOS should be ideal for people who are searching for something simple to use. If however you prefer to have a more personalised, free user experience, you could be more suited to an Android.
The dimension of a tablet should be the second factor you need to consider when picking the best rated tablets. Generally, the size of a tablet computer will range from 7 inches to 10.1 inches. The bigger screen would be beneficial if you utilize your tablet to enjoy movies or play games. However if you want more mobility, the smaller display must be perfect for you. Aside from the size of the display, you also need to consider the storage size. If you do not download a lot of games, music or movies, then the 16GB model must be enough for you. You must acquire the 32GB or the 64GB model only if you download a lot of games and great deals of movies.
It is incredibly significant for you to take into account how you will apply the tablet pc before choosing which tablet pc is best for you. Is it for work, such as taking notes at conferences and reading documents? Or will you be using it for entertainment, like watching movies and playing games? Even though you could use tablets to execute both roles, there are some which are more appropriate than others. Microsoft Surface Pro, new iPad, and Asus TF700T are excellent for the workplace and have added features for their target audience. Nonetheless if you are planning to utilize your tablet tool for entertainment, tablet computers like Nexus 7 or Kindle Fire could be great for you.
The battery life is the final point you should think about. Every tablet pc will have a different battery life. Elements like bandwidth consumption,the tasks you undertake, processor speed, display size and brightness, would certainly influence the battery life. Furthermore, you should keep in mind that networking using Wi-Fi will cause less drain on your device’s battery than connecting with 3G or 4G. Read the rest of this entry »
