Blockchain security consulting company Qusu Future said: When you browse the homepage of any company that sells data center services, you may find that the word "security" appears more than a few times.
As companies adopt cloud services, they host data in these electronic vaults, and the key assumption is naturally that they will set up strong defense facilities to defend against cyber attacks.
In most cases, this is true. Most cloud-related security incidents are caused by improper client configuration. For providers, there are too many losses, and there are processes, agreements, failovers, tools, and even physical personnel present to ensure that if something happens, the impact will be minimized. But whether it is a data center owned by public cloud giants such as AWS or Azure, or private hosting arrangements, colocation facilities, or on-site data centers, data centers have their own loopholes. Intrusions and downtime do happen. In addition to hardware, there is still a single point of failure-services run on the same software, and updates may cause problems across multiple regions.
"Everything will fail in the end. This is a universal fact," Peter Groucut, managing director of Databarracks, previously told TechHQ. In light of this, and as we trust them more than ever, here are some of the most common cyber threats facing data centers.
DDoS service
Distributed Denial of Service (DDoS) attacks are the most common type of attack. Norton, an antivirus software provider, called these attacks "one of the most powerful weapons on the Internet." In this kind of attack, hackers try to flood the website or crash the website or computer through excessive traffic, thereby making the website or computer unusable.
Netscout found in a 2018 report that 92% of US companies have suffered such attacks. DDoS attacks are a direct threat to the uptime of data centers. With the increasing number of IoT connected devices with poor security, attackers have more opportunities to build huge botnets to launch them. In June last year, "network congestion" caused Google Cloud downtime, during which at least 16 Google products were out of service-including the entire G-Suite, Gmail, GoogleDocs, GoogleDrive, GoogleCloud and YouTube.
Ransomware
Cybercriminals are now attacking corporate infrastructure with ransomware, and the damage may be widespread and long-lasting. For example, South Korean hosting company Nayana was attacked by ransomware, causing thousands of hosting client websites on its servers to go offline for weeks. Even after paying a ransom of $1 million, not all of them were recovered. In September, Equinix, one of the world's largest on-demand hosting data center providers, disclosed that its internal systems were attacked by ransomware, but fortunately, its core customer-facing services were not affected.
These types of attacks not only threaten customer data on the provider's server, but also completely destroy trust in the service. Data not only faces the risk of being released, but it will also be permanently changed, threatening the integrity of the data.
External access
When it comes to data center security management, external services, such as cloud access security agents or external DNS servers, are often ignored. Then, the attacker can target these external dependencies. Last year, NordVPN-its leading virtual private network service used by companies to protect sensitive data-confirmed that one of its data centers installed a third-party remote access system without notifying customers, resulting in insecure servers. To hacking.
In 2016, an attack on DNS provider Dyn caused service interruptions in Europe and North America, affecting services including BostonGlobe, CNN, Comcast, and PayPal.
Application attack
Although it does not directly affect data center services, attacks on web or server applications (such as customer dashboards or control panels) can still effectively shut down services by making them unavailable. Through brute force cracking, these malicious password cracking behaviors can be prevented. These attacks are more targeted and require less bandwidth, but they may eventually paralyze services.
Qusu Future, a blockchain security consulting company, said: The current Internet environment is becoming more and more complex, and network attacks are becoming more frequent. The impact and losses on major Internet companies are also increasing. In order to ensure the stable operation of servers , Qusu Future suggests that you must choose a professional network security company like Qusu Future for defense in advance, and don’t wait until the server crashes to find a way. The loss at that time will be irreparable.
