Cryptography And Network Security Behrouz Solution. Today, data breaches are more common than ever before. People want to know what they should do once their personal information gets stolen. Data breaches happen for a number of reasons.
But here are some of the top ways hackers get into your accounts and steal your sensitive information. Here are some.
Phishing:
Phishing is a type of scam that involves emailing people with fake links and attachments. The attachment may contain malware, which can then track your keystrokes and capture your passwords for you to see. It can also steal your identity by getting access to your email accounts or other sensitive information.
Exfiltrate Data:
Hackers have found ways to exfiltrate data from organizations as large as the U.S. government. If a hacker breaks into a database system and steals data, he or she might not be able to get the whole database; instead, they might try to download files individually so that they don’t set off alarm bells. This is more common with small organizations that don’t have the same level of security protection as larger corporations do.
Malware:
Hackers often use malware in an attempt to gain control over computers and networks so that they can steal information from them or cause damage in one way or another. The most common types of malware are viruses, worms, Trojans, and spyware (which includes cookies).
Some malware might try to capture keystrokes for passwords and account numbers, while others may attempt to take control of computers to install programs without any knowledge from the computer owner (known as “drive-by downloads”). Still, others are only for destruction purposes as “wiper” malware. Or such as one piece of malware called “Stuxnet” that was used against Iran’s nuclear facilities in 2010-2011.
Insider Trading:
Insider trading is a form of fraud where a person who works for a company uses his or her access to sensitive information about that company or its employees to trade stocks based on that information. This is illegal because while the person may have access to the information, it is not supposed to be used for financial gain. Insiders can include employees, directors, or even family members.

Firewalls:
A firewall is a software device or a hardware device (you can buy firewall routers at any large electronics store) that separates one network from another. For example, separate your business network from the Internet by a firewall to ensure that no unwanted data gets into your system or network.
A firewall is to prevent access to sensitive information, block email spam, conduct port scanning for security purposes, and more.
Intrusion detection systems
Intrusion detection systems are to monitor data transmissions over networks such as the Internet and check for signs of hacking attempts. Or other suspicious activity (for example, if an employee tries to access the database too much). Intrusion detection systems are also used to monitor physical events such as someone trying to break into your building or steal equipment off of your property.
