Morgan RileyCybersecurity refers to the steps that are taken to protect devices, networks, and data that are connected to the Internet from unauthorized access and use by criminals. In addition, cybersecurity ensures the confidentiality, integrity, and availability of data throughout its lifecycle.
Cybersecurity applies to both software and hardware, as well as information on the Internet. It can protect everything from personal information to complex government systems.
In a Nutshell
- Cybersecurity protects Internet connected devices, networks, and data against criminals.
- It protects data throughout its existence.
- Cybersecurity includes cyberattack prevention, detection, and reaction.
- As computers grow ubiquitous, cybersecurity is crucial.
- Cybersecurity must adapt to emerging technology to remain ahead of hackers.
- Phishing, spyware, eavesdropping, and DDoS attacks are the most prevalent cyberattacks.
- Phishing uses emails or texts to get sensitive information.
- Malware is destructive software.
- Eavesdropping attacks alter or erase network data.
- Denial of service attacks flood the system with traffic to block genuine users.
- Multiple sources launch distributed denial of service assaults.
Understanding Cybersecurity
Cybersecurity measures include the prevention, detection, and response to cyberattacks. Any information stored on a device, computer system, or network connected to the Internet can be hacked. With the right measures, this can be prevented. As the world relies more than ever on computers, cybersecurity has become essential.
Cybersecurity ranges from the simple to the complex. Most devices come with password protection as a basic safety measure to keep hackers out. Updating software is another simple way to prevent cyberattacks.
If a system is under attack or at risk of attack, specific measures can be taken depending on the type of attack. Encryption, for example, is one way to prevent attacks, and certain anti virus programs can detect suspicious online activity and block most computer attacks.
Cybersecurity is a shared responsibility and requires a collective approach.

To ensure the security of a system, it is essential to know the risks and vulnerabilities inherent in that particular device or network and whether hackers can exploit those vulnerabilities.
Cybersecurity measures must constantly adjust to new technologies and developments to stay one step ahead, as hackers adapt their methods to new forms of cybersecurity and render previous measures ineffective.
Types of Cyber Attacks
Cyber attacks can have far reaching effects on individuals, businesses and government organizations, including monetary losses, identity theft and reputational damage. They are classified according to the method of attack. Although there are many types of cyberattacks, some of the most common include:
Phishing
Phishing occurs when an email or text message appears to be sent by a trusted source. The goal of phishing is to trick the recipient into sharing sensitive information, such as credit card details and login credentials, or to install malware on the victim’s computer. Phishing is one of the most common attacks against consumers.

Malware
Malware is malicious software intended to cause damage to a computer or network. Types of malware include viruses, worms, spyware, and ransomware. Malware can be introduced to computers when a user clicks on a link or opens an email attachment that contains malicious software.
When inside the system, malware can block access to key network components (ransomware), covertly obtain information by transmitting data from the hard disk (spyware), disrupt components and render the system inoperative.
Listening Attacks
An eavesdropping attack (also known as a man in the middle attack) occurs when a hacker intercepts, deletes, or modifies data while it is being transmitted over a network by a computer, smartphone, or other connected device. Cybercriminals use network communications that aren’t secure to get a user’s data while it’s being sent or received.
Eavesdropping typically occurs when a user connects to a network that is not protected or encrypted and sends sensitive business data to a colleague. Eavesdropping attacks can be difficult to detect because, unlike other cyberattacks, the presence of an eavesdropping device may not affect device or network performance.

Denial of service (DoS) attacks target devices, information systems, and other network resources to prevent legitimate users from accessing services and resources. Most of the time, this is done by sending so much traffic to the server and host that they stop working or crash. DoS attacks are system versus system attacks, which means they come from one place and go after one system.
Distributed Denial of Service Attacks
Distributed denial of service (DDoS) attacks are similar, but the attack comes from multiple remote machines (zombies or bots). These attacks can be deployed much faster and with more traffic than DoS attacks, so they are often more difficult to detect than DoS attacks.
323,972
The number of people who were victims of phishing scams in 2021, according to the FBI. This is up from 241,342 in 2020, a year over year increase of 34%. The Internet Crime Complaint Center, or IC3, received an average of 552,000 complaints per year over the past 5 years, representing losses of $6.9 billion in 2021 alone.
Typical Targets of Cyber Attacks
While any individual system is at some level of risk of cyberattack, larger entities, such as enterprises and government systems, are often targeted because they store so much valuable information.
The Department of Homeland Security, for example, uses high tech cybersecurity measures to protect sensitive government information from other countries, nation states and individual hackers.
Cybercrime is on the rise as criminals attempt to profit from the vulnerability of business systems. Many attackers are looking for ransom. The average ransomware payment rose to a record $570,000 in the first half of 2021, according to a report from cybersecurity firm Palo Alto Networks.
Emily RobertsAny financial system that stores credit card information of its users is at high risk because hackers can directly steal people’s money by accessing these accounts. Large companies are often attacked because they keep personal information about all of their employees. The sectors with the most cyberattacks between November 2020 and October 2021 for attacks on core web applications are financial (226 incidents), healthcare (173 incidents), professional (164 incidents), public administration (158 incidents) and information (144 incidents).
Wrap Up
Today’s digital age requires cybersecurity. Cyberattacks can cost individuals, corporations, and governments money, identity, and reputation. Protecting yourself, your organization, and your data starts with understanding cybersecurity and frequent cyberattacks.
A comprehensive cybersecurity plan should include detection and response methods, personnel training, and software updates. To stay secure, you must stay educated about current threats and periodically analyze and upgrade your cybersecurity procedures. Stay watchful and ahead of hackers because they’re always changing their tactics.
