attack indeed she could have with the help of cyber security cyber security involves techniques that help in securing various digital components networks data and computer systems from unauthorized digital access there are multiple ways to implement cyber security depending on the kind of network you are connected to and the type of cyber attacks you are prone to so let's take a look at the various cyber attacks that anne could have been exposed to one of the most common types of cyber attacks is a malware attack like trojan adware and spyware to name a few had ann downloaded any suspicious attachments online her system could have gotten corrupted by certain malicious viruses embedded within the attachments next is a phishing attack the type of cyber attack which ann experienced here the hacker usually sends fraudulent emails which appear to be coming from a legitimate source this is done to install malware or to steal sensitive data like credit card information and login credentials another type of attack is the man in the middle attack here the hacker gains access to the information path between ann's device and the website's server the hacker's computer takes over anne's ip address by doing so the communication line between ann and the website is secretly intercepted this commonly happens with unsecured wi-fi networks and also through malware password attack is one of the easiest ways to hack a system here anne's password could have been cracked by using either common passwords or trying all possible alphabetical combinations to prevent future cyber attacks and sought to implement a few cyber security practices first she installed a firewall as the name suggests it is a virtual wall between anne's computer and the internet firewalls filter the incoming and outgoing traffic from your device to safeguard your network and they can either be software applications or hardware reinforcements secondly and implemented honeypots just like how flowers attract bees dummy computer systems called honeypots are used to attract attackers these systems are made to look vulnerable in order to deceive attackers and this in turn defends the real system in addition to these she also decided to use unique alphanumeric passwords antivirus software and started avoiding mails from unknown senders that was ann's story cyber attacks are not just confined to individuals but also to public and private organizations the cyber attacks carried out in such places are more deadly and they result in colossal losses motives of such attacks are many starting from tampering with crucial data to monetary gains let's have a look at a few of the cyber attacks that companies are subjected to various public sector organizations and large corporations face the advanced persistent threat apt in this form of attack hackers gain access to networks for a prolonged period in order to continuously gain confidential information companies also witness the denial of service attack where networks are flooded with traffic which in turn leaves legitimate service requests unattended a variant of this is the distributed denial of service ddos attack when multiple systems are used to launch the attack when a hacker manipulates a standard sql query in a database driven website it is known as a sql injection attack by doing so hackers can view edit and delete tables from databases amidst a plethora of cyber attacks it is indeed a challenge for organizations with several networks and servers to ensure complete security this is not an easy task and to help with this cyber security professionals are hired to work on identifying cyber threats and securing a company's network there are multiple job roles in the field of cyber security if hacking fascinates you then the role of an ethical hacker is something to be explored such professionals try to a network's vulnerabilities just like how a hacker would do but only to identify those vulnerabilities and resolve them for protection against an actual cyber attack but if you are looking to design robust security structures then the role of a security architect is more apt a chief information security officer ciso plays a crucial role in enterprise security and is entrusted with the overall safety of the information in an organization so here's a question for you identify the type of cyber attack where the hacker's system takes over the client's ip address a ddos attack b man in the middle attack c phishing attack d password attack give it a thought and leave your answers in the comments section below three lucky winners will receive amazon gift vouchers with the increase in the production of global digital data it is anticipated that cyber attacks will quadruple in the near future organizations are going to need cyber security professionals who can prevent these attacks a career in the field of cyber security is lucrative and a very smart decision for
