Protect Your Intellectual Property
You may be very vulnerable to online crime, but you don't need to be.
Information Security has always been a vital component of information systems, and ever since the rise of the Internet back in the early 1990’s, information systems have become increasingly accessible by people across the globe.
Today, security is one of the highest priorities in most organisations and more and more home users are getting the message and becoming aware of the importance of information security.
Just think for a moment - how much data is stored electronically by businesses - banks, building societies, insurance companies, supermarkets, and so on - records for each individual customer or client? How often do you use the internet? How many websites do you have information recorded on? This may give you some idea of just how much data there is out there.

THREATS TO INFORMATION SECURITY
IP spoofing refers to the technique used by people to unlawfully access computer and information systems, by using an IP address of a trusted host to connect to a network or to communicate with a computer or a server.
Before a hacker can use IP spoofing, they will first need to find a valid IP address for a trusted host by applying various techniques, and then once they obtain an IP address, they will need to modify the packet headers and include the new IP address to make it look like the packets are originating from the trusted host, not from the hacker.
Note that many routers and firewall devices (hardware and software) can protect against IP spoofing.
Non-blind spoofing is a type of IP spoofing attack that requires the attacker and the victim to be on the same subnet. The most common form of non-blind spoofing attack occurs when the hacker corrupts the data stream of an established connection, and then re-establishes the connection by using the correct sequence and acknowledgment numbers with the attack machine. Note that it is possible for an attacker to sniff the sequence number and acknowledgment numbers by using dedicated software, instead of going through the complex task of manually calculating those numbers. By using a non-blind spoofing technique, the attacker can use a pre-established connection, thus bypassing any authentication measures required before establishing a new connection.
Blind spoofing is a type of sophisticated IP spoofing attack whereby the attacker needs to sample the sequence numbers because the sequence number and the acknowledgment numbers are unreachable. To do so, the attacker will need to send many packets to the target computer and attempt to sample sequence numbers. This task was relatively easy in the past because computers used to generate sequence numbers using basic techniques. Sampling sequence numbers is becoming increasingly difficult today with the advances in technology, because most operating systems generate random sequence numbers, so it’s pretty difficult to predict them accurately.
“Man in the Middle” attack
A man in the middle attack (also called “MITM attack”) is a term used to refer to both blind spoofing and non-blind spoofing attacks. A man in the middle attack occurs when a malicious party intercepts a communication between 2 legitimate parties. By doing so, the intruder will be able to view, modify, or delete information flowing between the 2 parties without being noticed by the sender or the receiver.
A man in the middle attack is mainly used by attackers who would spoof the identity of the original sender and then proceed to fool a victim into disclosing confidential information to them. The sender will most likely disclose the requested information because they would believe that they are dealing with a trusted recipient.
“Denial of Service (DOS)” and “Distributed Denial of Service (DDOS)” attacks
Denial of service attack is one of the most common and most harmful types of IP spoofing attacks used by crackers to flood a computer network with requests which will consume the network bandwidth and network resources. It is very difficult to defend against a denial of service attack. To perform a denial of service attack, crackers will need to flood the victim network with as many packets as possible in a short amount of time. The reason why this type of attack is difficult to track and avoid is because crackers can spoof the source IP address for the attacker machine and make it look like the packets are being sent from a legitimate computer connected to the network.
A distributed denial of service attack is another type of harmful IP spoofing attack and very similar to a denial of service attack. The main difference between a DOS and a DDOS is that a DDOS requires multiple machines to participate in the attack and sending spoofed traffic to a victim network, whereas a DOS attack only requires one machine to send the spoofed traffic.
Phishing is term used in the world of information security; it refers to a fraudulent attempt to steal a user’s personal information (such as usernames, passwords, date of birth, credit card numbers, bank account logins and passwords, etc.). The main purpose of phishing is to steal money form users, whether from their emails, phone calls, or websites logins (such as internet banking logins).
When an attacker installs malicious software on a computer, they will be able to steal the personal information of the users off that computer (note that these attackers are known as “cyber criminals”). Another way cyber criminals can steal the personal information of computer users is by applying social engineering to convince them to hand over their personal information or to install malicious applications under false pretenses.
Users need to protect themselves against phishing attacks, and the most important thing they need to do is to educate themselves about phishing attempts to be recognise them and avoid them.
For example, let’s consider phishing emails. When a user receives a phishing email, the email would appear to come from a well-known organisation (such as web mail sites, online banking sites, financial institutions, universities, government websites, etc.) and the email would generally ask the user to enter their personal information (such as their username, password, pin numbers, social security number, credit card number, bank account details, etc.). The easiest way to tell that a particular email is indeed a phishing email is if the email was sent from a site where the user doesn’t have an account. Another way to recognise a phishing email is when an email contains a link to another website. Often, phishing emails would contain a link that opens a new website when the user clicks the link, and the website with almost always request personal information from the user. The reason why such emails are classified as phishing emails is because legitimate organisations would never request the user’s personal information via email.
How to defend against spoofing
Spoofing is a very serious computer attack and it is very important to attempt to limit the damages and protect the computer systems and computer networks against the risks of spoofing attacks.
- Filtering at the router
The first step you need to take to implement a layer of defence against spoofing is to apply filtering at the border routers. This can be achieved by implementing access control lists (ACL) to block private IP addresses on the downstream interface, and block IP addresses outside the valid IP range on the upstream interface. This will prevent people connected to the network from sending spoofed traffic onto the internet.
- Encryption and authentication
You can also implement encryption and authentication to reduce spoofing threats and make sure that authentication is carried out over a secure and encrypted channel.
