Hacker (computer security) [updated]


Computers with Image-inationIn the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, or challenge. The subculture that has evolved around hackers is often referred to as the computer underground but it is now an open community. While other uses of the word hacker exist that are not related to computer security, such as referring to someone with an advanced understanding of computers and computer networks, they are rarely used in mainstream context. They are subject to the long standing hacker definition controversy about the true meaning of the term hacker. In this controversy, the term hacker is reclaimed by computer programmers who argue that someone breaking into computers is better called a cracker, not making a difference between computer criminals (black hats) and computer security experts (white hats).Some white hat hackers claim that they also deserve the title hacker, and that only black hats should be called crackers.

10 PC security mistakes we ALL make   
Revealed by hackers

Not one knows security mistakes much better than hackers - because for them, small errors in safety are really the ‘keys’ that allow access to home PCs and additionally office computer systems.

And also hackers are obvious about one thing. Computer consumers render mistakes every the time - and additionally often the same ones, continuously. A couple of hackers - one ‘ethical hacker’, who tests computers by attempting to burst into them, and one ex-hacker that today functions in safety - lay bare the ten errors which crop up most frequently.



1. Don’t use the same username everywhere
‘People often upload photos of themselves with an online collection, assume,’ says Cal Leeming, a former hacker that functions in security at just Simplicity News, ‘However they utilize a username they utilize upon some other websites. The couple don’t realise that people can use Google to connect them around all the different worlds the couple visit, and also then work out a way in.’

2. Don’t trust public wi-fi
‘Whenever you go on a public wi-fi network an individual have no way to determine whether or not it is an actual system run by a established company, or a fake run by a spotty man alongside an individual,’ can say Tom Beale of Vigilante Bespoke. 'The difficulties especially bad on top of cell phone, in which you truly cant tell if in case you re on a fake network package up to steal the data. Should you decide re going to use public systems for your business, utilize a notebook, because the internet browser could inform you of safety breaches - the cellphone won t.’

3. Be careful about who you friend on Facebook
‘Facebook has got been basically forced to apply privacy options,’ says Cal. ‘But people still purchase it wrong. The couple randomly friend other individuals, not realising they are really providing away information which can feel useful in a cyber battle - for example names of pets or family that could be a password or perhaps security concern.’

4. Don’t trust people you don’t know
‘I always tell individuals to try to do one ‘offline test’ - ie would you do the same thing  if you were in the real world? So for example, should you decide re chatting to someone on the internet, and also you tell them some information, might you give that information to someone you d simply met wearing a bar?,’ says Tom. ‘Online, an individual re actually LESS low risk  - since you may well not be speaking with whom you think an individual are. Individuals just seem to lose all of the idea of actuality once they re for a PC.’


5. Use two-factor passwords when you can

‘People resist this except once they re designed to do so - such as by their bank,’ say Tom. ‘Though it does put in which extra covering. It does provide coverage. Individuals accept that their bank will utilize tokens or keycard readers, but when different sites put in it, individuals resist it - they simply want quick access.’
 
6. Don’t re-use your email password 

‘This isn’t going to become a problem that goes away just about any time later on,’ says Cal. ‘People don’t realize what are the concerns of using the exact same security. Should you decide reuse the e-mail security, you re handing out the keys to be hacked and breached - giving hackers access to the data the couple ll want to hack the banking account and also other systems you may use. Individuals utilize simple passwords for efficiency - memorising too many is actually a soreness.’ 

7. Don’t be fooled by ‘cries for help’

‘A few of the a large number of effective attacks are "cries for help" from buddies - delivered by e-mail from a compromised machine. It is incredible the actual number of individuals answer to which,’ can say Tom. ‘If or when its a person which travels a lot, and also their e-mail is hacked, it is more persuading when you get some kind of email suggesting that they are stranded overseas, and want cash. They goal those that have a scattergun approach, but once they find somebody that IS overseas a lot, it is extremely effective.’

8. Use antivirus software

‘I cannot see just about any reason why you wouldn’t run AV software,’ says Tom. ‘It is not a Holy Grail, though it may help you to contract with the vast majority of known difficulties. Browsing with no it is like driving with no seatbelt. Its very first film of defence, whether you re using PC, Mac or perhaps Android.’


9. Remember that funny videos can be very unfunny

‘Facebook’s system doesn’t filter for malicious hyperlinks, so that they can be extremely risky. Frequently a ‘movie link will try to fool individuals directly into checking out the infected internet site or perhaps getting an activity in the guise of movie software or fake antivirus software. The only defence will be to think, ‘Might my friend really post that?’ so be careful regarding people you only half-know. Facebook and Twitter require to inform users better.’


10. Set everything to auto update

‘Attackers can be actively appearing for vulnerabilities - not simply in the operating system, but in the browser, in plug-ins for example Flash and additionally Java. Be certain which all of those are up to date,’ can say Tom. ‘If in case you don’t, you will be leaving protection holes. The vast majority of updates don’t add functions, they just fix holes, and if or when you don’t get them, you have the gaps.’
