Reliable Signs that Website Security has Been Breached
Until relatively recently, attacks against websites were fairly easy to spot. In most cases, the hacker or hackers behind such attacks defaced vulnerable websites or simply caused them to crash. Such attacks were typically mass scale in nature and were designed to cause as much damage as possible to a very wide number of targets. In contrast, many of the web attacks these days are far more targeted and stealthy in nature and are designed specifically to evade detection by anti-malware tools and intrusion detection systems. The most common modern goal behind website attacks is often to steal sensitive information such as customer data, financial information and customer data or to extort money from targeted businesses. Detecting such website security compromises can be challenging, but even the most sophisticated attacks often end up leaving telltale signs.
One reliable sign that website security has been compromised is when an internal system suddenly begins to transmit data to an unknown IP address. Web attacks are often launched to steal data from the underlying Web servers and the systems that are attached to it. The theft is typically carried out using malware programs that are capable of sniffing out specific pieces of information and then stealthily sending it out to a remote server from where the stolen data is collected by the attacker. Sometimes, the stolen data can be sent out in a continuous stream via commonly used ports, or sometimes in can be sent out in batches at previously scheduled intervals. In either case, such data transmissions are a good indicator of compromised site security. The rogue traffic can be hard to spot without the proper malware detection and network monitoring tools.
Unexplained traffic slowdowns can be another sign that website security has been compromised. Hackers often employ what are known as distributed denial of service (DDoS) attacks to disrupt a websites operations. In a DDoS attack, the network connections linking a website to the Internet become clogged up with useless data packets making it very hard for legitimate traffic to get through. Such attacks are very common these days and are often used to extort money from targeted websites. Dealing with DDoS attacks can be extremely challenging and often require companies to add extra network capacity and traffic filtering tools.
One of the most obvious signs of a website security compromise is when it starts serving up malicious code, adware or spyware programs. Hackers often compromise reputed and well-known websites and use those sites to distribute their malware programs to unsuspecting web page visitors. The malware programs can be hidden in banner advertisements or on other parts of the site and get automatically downloaded onto a visitors browser. Such compromises are often hard to find, but can be detected using website malware monitoring and malware detection tools.
Windows Hard disk Failure and Recovery
Windows is one of the most popular operating system and it is widely used by computers and servers due to its convenience and good performance. Hard drive is hardware placed on all computers storing data and installing program and Windows. When hard disk gets damaged, the result is losing important data or even system. Hard disk problem happens to all computers without any foreshadow and there are a great number of causes of HDD failure such as virus attack, bad sector, sudden power failure, etc.
All HDD problems can be divided into two groups: physical failure and logical failure. This post will explains both and their differences.
Hard drive physical failure
Hard drive contains many mechanical parts which easily get damaged after violently crash or dropping to grand. It has been mentioned just now, sudden power failure may cause severe problem. It’s well known that traditional hard drive writes and read data by way of heads moving forth and back above rotating platters. Normal process of system shut down sends signal to hard disk and heads will withdraw. But sudden power outage forces heads to withdraw from stack of moving platters, which is very likely cause bad sectors and do harm to head and data.
Solution of such HDD failure differs from the importance of missing files. Some users seek hard drive recovery solutions while some want get HDD repaired. However, in fact, neither of them is easy to realize, as certain damage is irreversible and even specialized machines can’t handle it.
Logical hard drive failure
As it suggests literarily, errors or problem happened on logical level. An easy example, hard drive partition becomes inaccessible or corrupted because of file system error. Reasons of file system error are many, which can be virus infection, unplug drive improperly or partition table damage. Windows hard drive failure brings about data loss, as corrupted partition or drive can’t be opened.
It’s easy to fix such issues. Formatting is able to make an inaccessible partition normal again and chkdsk command helps fix file system error. One point should be noted is that Windows data recovery must be done prior to formatting or any other repairing actions; otherwise recovery result will be affected, as files might be damaged.
Hard drive failure repair and data recovery
The most common hard drive damage is bad sector. To some extent, bad sector also can be further divided into two types: logical and physical bad sectors. The former can be fixed by some software, and yet physical bad sector requires professional machines. However, there are still many bad sectors can’t be repaired. Besides, once heads within the hard drive go wrong, it is not workable to get it repaired.
HDD failure won’t be repaired on its own and lost files won’t be recovered automatically either. Thus third party tool or service is needed, for instance hard drive recovery software Eassos Recovery is capable of retrieving missing files from damaged HDD. There are many online and local HDD repairing shops aiming to fix physical problems.
