Network attack

It is reported that ,2020 year 12 Mid month , A network Safety company Accellion It's been attacked The hacker attacks , Hackers are breaking in Hundreds of Accellion Enterprise customers of , And stole Sensitive document . thereafter , Hackers Leaking data As threat Conditions , towards Accellion Asking for ransom . according to the understanding of , The number of enterprises affected this time is as high as A dozen , and Accellion Just one of them . More or less, these enterprises have suffered serious Data theft impact , Its customers suffer Huge losses .

so , In the digital age , The importance of network security is self-evident .

In the past few years , Network security loopholes And Cyber attacks it is often seen , This makes some enterprises and IT Service providers are under great pressure .“ Enemy and know yourself , Only in this way can we prevent trouble before it happens ” This is the eternal truth , therefore , Enterprises should not shy away from medicine , Get to know The true face of network security vulnerabilities Is the first step to defeat them .

According to the paloalto company The latest data from , External researchers are upstream Telnet Found in the code Telnet Remote code execution (RCE) Loophole ：

• Before an attacker attacks the enterprise network No permission required , Therefore, it is not necessary to access the settings or files of the vulnerable system to perform the attack ;
• Attackers can No user interaction Using vulnerable systems for network attacks ;
• The exploited vulnerability can only affect Managed by the same safety organization Resources for , Systems under the same network are vulnerable to attacks .

data display ,Telnet Remote code execution (RCE) Loophole The degree of attack is more complex , stay paloalto The vulnerability cases published by the company have been up to 8.1 The evaluation score of , Obviously, the attacked enterprises will be seriously affected ：

• Confidentiality affects —— Enterprises may Complete loss of confidentiality , Cause... In the affected components All resources To the attacker ; May also be , Attackers gain only limited access to information , But the information disclosed will have a more serious impact , such as , The attacker stole Administrator's password or Web Private encryption key of the server .
• Integrity affects —— Enterprises may Complete loss of integrity or Complete loss of network protection , such as , The attacker can modify Protected by the affected components All the files ; Or maybe , The attacker only modified certain files , but Malicious modification It will bring very serious consequences to the enterprise .
• Availability impact —— Enterprises may Completely lose control of the server , An attacker can exploit the vulnerability repeatedly , Each attack will leak a small amount of memory , Repeated attacks lead to The server is completely unavailable .

There are many types of cyber attacks , The above is just one example of an attack . In reality , Cyber attacks do not change with the size of the enterprise , All enterprises should pay attention to network security .

Usually Branch enterprises In order to expand business, I will choose SaaS Wait for Cloud Services , In order to achieve App upgrade And cost reduction Purpose , and Tradition MPLS Network connection scheme Of Security cannot And Saas Application phase matching , Not to mention its automated configuration capabilities .

therefore , More branch enterprises choose SD-WAN Provide change Safe and reliable And Efficient and agile The network plan of .SD-WAN The plan passed a Simple platform , Provide... For the enterprise Convenient network connection And Reliable network security . For enterprises that choose cloud services Unified network operation and maintenance platform , from Cost savings Start , Real time monitoring of security vulnerabilities and Network attack Behavior , Reduce the complexity of the overall network structure , Let enterprises use A risk-free security network .

If you are looking for a safe and reliable network solution , Take a look at the seasonal coronal flash nebula SD-WAN Network plan , I believe you will get different surprises .
