So what exactly does cybersecurity do in the face of a possible cyberattack at any time? Before we know about cyber security, we should also know about our “enemy” cyber threats。
Common types of cyberthreat
There are currently six major types of cyberthreats on the internet:
Malicious software
Malicious software is a broad term that includes any document or program that damages or damages a computer. For example, extortion software, zombie network software, spy software, wooden horses, viruses and worms can cause computer damage by providing unauthorized access to hackers. The more common form of malicious software attack is when the malicious software disguises itself as a legitimate document, thus circumventing detection。
Ddos attack
The ddos attack was a malicious act to disrupt the normal flow of target servers, services or networks by flooding the target server or the surrounding infrastructure through large-scale internet traffic. It uses several damaged computer systems as a source of attack traffic to achieve impact. The machines used may include computers or other networking resources (such as iot equipment)。
Net fishing/social engineering
Net fishing is a form of social engineering that induces users to provide their own pii (perso)Nal identifiable information, personal identifier) or sensitive information. For example, cyber-frauds, many of which we must have heard, are disguised as e-mails or text messages of legitimate companies in which users are asked to provide privacy information such as bank cards, passwords, etc. The e-mail or text message appears to be from a regular legal company, requiring users to provide sensitive information, such as bank card data or log-in passwords, but in practice your personal information is stolen as soon as you complete the input. It is also a reminder that there is no trust, no disclosure and no transfer of suspected fraud。
Continuing high-level threats (apt)
The apt attack, also known as a targeted threat attack, is an ongoing and effective attack by an organization against a particular target. Such attacks are extremely covert and targeted, and often employ advanced, sustained and effective threats and attacks using a variety of means, including infected media, supply chains and social engineering。
Intermediary attack
Intermediaries are a wire-tapping attack, with hackers intercepting normal web-based communications data, tampering and sniffing with data without the knowledge of both parties. For example, on the unsafe wi-fi network, attackers can intercept data transmitted between visitor equipment and networks。
Internal threats
Current or former employees, business partners, outsourced service providers or anyone who has visited the system or network may be considered an internal threat if they abuse their access rights. Internal threats may be invisible to traditional security solutions that focus on external threats, such as firewalls and intrusion detection systems, but are also the least to ignore。
How can the network be made safer
While we cannot prevent an attack from its source, adequate preparedness and precautions can minimize the damage. And that's what cybersecurity is about. Cybersecurity can be divided into roughly three parts:
Security of equipment
Security of equipment, which is a physical storage of data, iteration, etc., or server, hard drive, etc., is the material basis of network security and the first consideration of network security. If your equipment is damaged, then whatever operation you do, it's useless。
Usually, we consider the security of equipment systems to consider the following:
In the case of personal computers, for example, we want to keep the system version up to date, including operating systems and all applications. And you need a good anti-virus program and a good firewall。
Data content security
In general, what we call content security is that the data content is consistent with national laws and regulations. But besides the security of encryption and transmission of content itself, there are two types of encryption that are currently used:
Operational behaviour security
The operation of the network can also threaten the safety of the network. According to statistics, more than 80 per cent of security threats to enterprises are due to the lack of effective management methods and strict systems of authority, leading to the active or passive disclosure of large amounts of data information by internal personnel using networks and equipment via mobile devices or networks. Among the types of threats in social engineering, criminals gain confidence by pretending to be internal employees by using corporate information in their possession, thus further acquiring internal confidentiality。
As the internet continues to evolve, cybersecurity will become increasingly important and the direction it involves will certainly become more comprehensive. When you are working or studying programmers, think about what else you can do, think about the direction of cybersecurity。
