The cybersecurity landscape is a dangerous one, as sophisticated hackers continue to wreak havoc on computer owners worldwide.
The cybersecurity landscape is a dangerous one, as sophisticated hackers continue to wreak havoc on computer owners worldwide. A recent study by PandaLabs indicated that approximately 32 percent of all computers studied had malware, with at least 27 million new strains created in 2012. Trojans accounted for 75 percent of all malware attacks produced last year.
Viruses accounted for 8 percent of all of these incidents, according to the company, followed by worms with more than 6.4 percent.
This is not the only frightening trend discovered by PandaLabs. The popularity of social networking websites is putting consumers in danger of having their passwords exposed. For example, a security breach of LinkedIn led to the theft of 6.5 million passwords.
Consumers should do all they can to avoid being a victim of a major security breach. Industry professionals encourage people to use a password manager like Sticky Password to avoid using the same phrasing for each online account. If a cybercriminal can obtain a common password from someone, the malicious individual may have access to a person’s email, banking information or other sensitive information.
Mobile devices are another dangerous platform that can impact users and their data and passwords. PandaLabs said that the Android operating system is the most popular for cybercriminals looking for ways to steal information and money.
Smartphones powered by Android or Apple are likely to remain popular targets as more people adopt smartphones. Owners of the iPhone can also download password managers to their devices to ensure their information remains protected while browsing from their mobile gadgets.
With so many interactions taking place through the internet and via multiple devices, hackers will continue to target users involved with these popular channels. Consumers should strongly consider doing all they can to safeguard their most important information.
One widely observed problem in a recent online security survey was the systematic weakness of passwords throughout organizations.
As long as there is value to be gleaned from illegally breaking into computer systems, the threat will never be entirely gone. The recently-released Trustwave Global Security Report 2012, which evaluated the current conditions of online security, found a number of different methods through which data could be illicitly accessed. While some are complex, highly advanced methods with equally complex solutions, one widely observed problem was the systematic weakness of passwords throughout organizations, with entire departments placing themselves at risk through generic and easy-to-guess passwords.
The survey’s authors noted that the most widely used password among respondents was “Password1.” Containing upper-case and lower-case letters as well as a number, it fills many systems’ security requirements and is easy to remember. Its prevalence, of course, makes it extremely easy for prospective hackers to guess. The survey-takers found system operators settling for default passwords in many parts of the IT infrastructure, with firewalls and routers likely to have no password, or a generic and unchanging word in place. The survey also identified risk stemming from users’ employing the same passwords across systems at work and at home, whether the data within was critical or not.
Weakness does not mean passwords as a system are doomed or need to be replaced. At the RSA Coneference 2012, online security expert Dan Kaminsky affirmed the strength of proper password technology usage. TechTarget reports that Kaminsky remained unconvinced that technology such as biometric authentication is ready to replace passwords, emphasizing that a fingerprint scanner is easier to fool than a well-chosen password.
“You know what’s amazing about passwords? They totally work,” Kaminsky told the conference audience, the source reports. “The fundamental ‘win’ of a password over other technologies is its utter simplicity and mobility.”
Users can gain the benefits Kaminsky describes while negating the risk from the Trustwave survey by selecting better passwords. Careful users, especially those with password manager software, are able to put up a key barrier between themselves and outside attackers. Keeping a variety of hard-to-guess passwords and changing them frequently is not simply a good idea, it can be the difference between a safe and unsafe system. Guessing “Password1,” typing it in and accessing private information takes seconds and requires no illicit software at all. Giving hackers such an opportunity is a critical mistake.
Recently I’ve wrote a script to calculate the swap usage and triggered the alert when Swap usage hit the certain level.
And I found out the actual memory usage is not using as it is where swap still caching the usage. To clear the swap cache and make the memory usage only, you may turn of swap by selecting the swap drive.
First of all, you need to identify the swap disk. Check the blkid for more information.
Look at the entry of swap. Assume swap is in sda5.
