The challenges facing CIOs in the field of cyber threats are extensive, especially as networks evolve at an increasingly intense pace. With the fusion of physical and virtual environments, and with the emergence of a range of resources based on IoT and endpoint, the attack surface has become bigger and more dangerous in the corporate universe.
Did you know, for example, that 1 in 5 small and medium – sized businesses affected by ransomware closes its doors immediately after an attack? Worse is to see that, for some years now, hacker attacks have been growing in Brazil at a much faster rate than in the rest of the world: in 2015, the invasions registered in the country increased by an impressive 274% ; in 2016, cases of attacks to take sites down grew 138% . The risks are diverse and from multiple perspectives.
But how to reduce the exposure field of systems and servers in an era of ffxiv data centres hijacking, vulnerabilities arising from IoT , and where even SSL encryption is used to hide malware, spy on the network and execute malicious traffic? Today you will learn about effective measures to protect your network perimeter and prevent damage to servers with critical functions in your company! Check out!
Do you know what a server attack surface is?
It is the extent of penetrability in a system or in servers. The smaller this surface, the more robust the security infrastructure of the organization’s computer systems. This rigidity is not acquired with isolated security tools, but with a systemic approach, which integrates and automates the existing protection resources, forming a complex real-time monitoring and correction ecosystem.
In 2016, an avalanche of DDoS attacks against DNS provider Dyn brought down much of the internet in the U.S. PayPal, Netflix, Airbnb, Spotify and Twitter were some of the services that went down due to the Mirai malware, which took advantage of vulnerabilities in multiple ports and connected systems.
Cameras and DVRs were some of the devices used as a starting point for the attack, a fact that makes it clear that the large amount of equipment connected today (such as GPS systems, robots in smart factories and holters used in hospitals), if not managed together. , render any information security initiative useless (since they expand the attack surface).
In this perspective, solutions in managed firewall, anti-DDoS backbones, special backup devices with encryption and dedicated servers are some features that can be implemented globally in your systems, guaranteeing customized dimensioning, high performance and protection of critical information.
Why has the emergence of new technologies been followed by an increase in cases of invasions?
There is no way to completely eliminate the attack surface, but there is a way, through a new way of thinking about the security fabric of your company, to significantly reduce the possible presence of vulnerabilities.
The central point for excellent IT security is to understand security projects as inseparable parts of the application design itself, developing and updating within the software life cycle (and not gradually adding).
Another important issue is knowing how to diagnose the exact limits of your security perimeter, especially at a time when almost all information is processed in the cloud.
In other words, as new technological solutions cause many activities to be performed outside the range of sight of traditional protection features, incident monitoring is head-on compromised. It is here that cybercriminals see fundamental loopholes for undue access.
What are the measures to reduce the attack surface on your company’s servers and systems?
1. Implement an intelligent firewall solution
An intelligent firewall solution is broad and proactive, helping, for example, to effectively combat DDoS attacks .
This is because this type of solution allows complete control of the work environment, through filters and rules for using the resources present. Features such as Access Rules, user authentication and antivirus gateway (which performs the filter of viruses originating from the external environment in the protocols HTTP, FTP, IMAP, SMTP etc.) are some of the tools that shield your network from third party accesses, protecting your servers and the availability of your applications.
2. Reduce the attention to security already in the programming phase
Did you know that the attack surface can be increased even in the programming phase of your website or web application? Just a hidden tag that contains a “clue” about your systems and a door will be open to an attacker.
There are situations in which, when viewing the source code of an e-commerce website, for example, hackers are able to access even payment server data, putting the entire retailer’s business at risk.
3. Carry ransomware decryption tools
Are you afraid of falling victim to a locker? You can prevent yourself from permanently blocking your ffxiv data center split by implementing ransomware decrypters , capable of decrypting your files without having to pay even R $ 1.00 for a ransom. Anyway, this type of instrument must be used in conjunction with other tools, such as an online backup solution.
4. Do not give up backup resources for mission critical servers and workstations
A remote backup system for companies allows:
automatic scheduling of backup copies;
compression and encryption of the selected files with a password;
restoration of multiple selected files;
among other facilities, which ensure robustness, reliability, availability and performance for your most important data.
5. Have a strategy for constant monitoring of server entries
Permanent management and real-time alerts are critical to keeping your servers safe, as they reduce response time to attacks and prevent the spread of threats.
Considering that hackers’ actions are generally based on social engineering (such as phishing) or exploiting known vulnerabilities for ftp servers, improperly configured network devices, among other predictable weaknesses in the corporate world, having their entire voice and ffxiv world statusinfrastructure constant monitoring significantly reduces the chances of intrusions.
