Denial of service (DoS) attacks are defined as attacks that prevent legitimate users from gaining access to information or services. The attackers can affect your system by the networks of sites you are trying to use or by targeting your personal network and computers. Most DoS attacks are done by flooding the targeted network with information keeping the server from processing your access request packet. A DoS attack can also be deployed against an email. Whether it is a business email or a personal email, the attacker can deploy the attack by sending lots of emails to the account. This works because most email services assign a set quota that only allows a certain amount of data in your account at a time. A term that is often misused is Distributed Denial of Service, or DDoS. This type of attack occurs when the attacker uses the victims system to attack other systems by taking advantage of security weaknesses or vulnerabilities. The attacker uses your system to send very high quantities of data to other systems or servers. There isn’t a whole lot that you can do to completely prevent being a victim, however there are steps that can be taken to reduce the chances that you become a target. First you can install and maintain anti-virus software. Second, you can install a …show more content…
However these symptoms don’t always mean that you are being attacked. There could be a problem with the network you are on or administrators may be performing maintenance. The first, and most common symptom, is that you network seems slower than usual. Whether you are browsing or watching a video this is a symptom that will effect anybody. The second, and most obvious symptom, is the inability to access any website. This symptom is, for obvious reasons, very noticeable. The third symptom you might notice is a major increase in the quantity of spam messages on your accounts. The last symptom is the inability to access a specific

The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
It seems that DOS attacks and other forms of cyber attacks are not under Computer misuse Act legislation ( misinformation and ignorance from many sources such as some webs of IT security specialists) but after consultation with an international law firm that doubt was resolved,and Compuer Misuse Act encompasses a wide range of activities including DOS attacks.
Treat any emails with respect & confidentiality i.e. do not share with anyone that should. Never walk away from your computer so that someone else can read your emails or even worse be in a position where someone could send an email on your behalf.
Network modification is one of the action to be considered when DDoS attack occurs. In this situation incident response team could switch to different network by using domain name system (DNS). IP address are translated through DNS by their domain name and DNS and DNS responsibility is to allow the user to securely browse into any websites. Also, DNS allows to send and receive emails through any web browsers in any website. Incident team should distribute the attack traffic across the network of data center so it will delay the DDoS attack in spreading into other networks. At last, traffic should be sent to high capacity networks so it can go through scrubbing services.
As a result, the emails of the senders bounce back. Unauthenticated Email Account or Mail Server: You will receive bounce emails if you try to send messages to an unauthenticated email account unknowingly. Symptoms of AT&T Email Error 553 Cannot send or receive emails to the email
February-The now infamous DDoS attacks against websites like Yahoo, eBay, CNN, and eTrade took place, leaving the sites offline for hours.
To stay safe from many different forms of viruses, the best way to go is to download a couple different kinds of anti-virus programs. Harley says it is almost impossible to get through three different anti-virus programs. He also says that it is easily solved when it comes to Trojans, worms, viruses, and malware. If you do not grant access to unidentified or unsafe programs, then it is very hard for viruses to be granted access onto your computer.
However, there are the wrong way of using email which are; Harassing or ban threatening emails Spamming or send large attachments or documents of un solicited emails Sending confidential information For long-term storage These are the incorrect use of emails in Apple, and there are codes of practice on the correct use of email in Apple. Points above are incorrect and correct way of using emails, these are because sending large or confidential documents can crash the software or may not open as the software does not support the file, also confidential information can be misused, long term storage is misuse of email as they should be recycled. Apple also have codes of practice on the use of the internet, where employees can and cannot use the internet for.
attempt to force a network offline and unavailable to its intended users. This process is typically performed by flooding a network with communication requests until the server cannot respond to the traffic, thus making the server go offline and become available. This process is relatively simple to perform to the average person through online programs. Since it is so easy perform, it has become a rising issue simply because anyone has the ability to hack into various servers. One example in recent news of DDoS attacks comes from Riot Games, developer of the popular online multiplayer video game League of Legends. After a month of inconsistency with their server stability and frequent shut downs, Riot Games reported that within the l...

Let’s start by defining spam; irrelevant or inappropriate messages sent on the Internet to a large number of recipients. Microsoft defines spam as an unwanted email trying to get information or sell you something [1]. This could be a fake email from your bank saying you need to authorize yourself, or even just a flyer trying to sell you anything from male enhancement to clothing. Next up let’s explain how to prevent spam mail. According to Vitaly Friedman the single biggest and easiest thing is to not say your email anywhere online [2]. He suggests that you have 2 email accounts one for personal or business contacts that is used only for personal emails to people you know and trust and the other is the one you put online to register for websites etc. So you’re probably wondering why spam is so bad if it’s just annoying emails of something trying to sell you something well there’s one more thing to worry about, viruses. Some spam is really easy to tell if its fake but others aren’t so easy [3]. Some spam is made to a “T” to look exactly like a big company and when you open them you could get a virus. These viruses could be anything from malware to hard drive corrupting computer killers. Finally let’s talk about how to remove spam. If you are getting spam unfortunately there is no way to stop spam once you are getting it. However there are ways to make sure you don’t see it. First let’s talk how about deleting, if you are getting spam there is nothing stopping you from just deleting the message [4]. Secondly there are ways to make sure you don’t see it. According to Adam Dachis just about every email server has a junk mail folder to separate spam. The server analyses the address and decides if its spam and if it is it ...
...ntial information from a user. Luckily, there are reliable ways of defending against them. The most reliable way is to install strong security software that has the capacity to defend against the multifaceted forms of threats. Avoiding P2P file sharing sites and scanning email attachments before downloading them are also a surefire way of protecting a computer against malware threats. Basic acts like using an updated browser and allowing Windows updates to install and update themselves are also necessary to keep a machine safe. Furthermore, checking validity of individual website addresses and installing authenticated software can also help a computer user remain safe from potential data theft and possible damage of useful programs. It may also pay good dividends to backup files. In case of a lethal malware attack, backed-up files can always be recovered easily.
