Defensive in the New Era of Network Security

Network Security developments are increasingly complex, threatening all organizations, businesses and citizens.

A not-so-peaceful era

Digital ​​peace that never shows signs of change in an undeniably unpredictable, particularly the world IoT (Internet of Things) quickly developing extensive is likewise the chance to work the malware found. Numerous IoT gadgets need security highlights, though they are typically just ensured with a default client name and secret key, for example the current disclosure for IP camera frameworks. Area name specialist organization Dyn US under assault from DDoS extraordinary in late October that the nation's many Web locales are influenced, even some administration blackouts, is a notice for the future once more. The cause was resolved to be brought about by Mirai, another sort of malware can make huge botnet by tainting through Internet associated gadgets. 

Numerous specialists caution that digital assaults progressively more intentional, and take hours as well as damage assaults tend to profit, for example, blackmail by ransomware malware is not new but rather developing seething all over the place. Vo Do Thang - Director of Training Center and Network Security Administrator Athena, share, he consistently got tests of ransomware by units sent to due process. The issue is that fast development of new ransomware and brought forth various varieties, is greatly hard to manage, while the creator concealing "give" to the group and sharing conveyances to use to assault the profiteers, ought to nearly not be discovered. Anybody can make ransomware from the first source code downloaded from the network has made the business earned tremendous illegal benefits for offenders. 


Cyberattacks to profiteering has turned into a lucrative business, mirroring the size of information burglary is developing. Simply late last September, Yahoo authoritatively affirmed around 500 million client records were stolen by programmers in 2014, including the delicate individual data of clients: name, login secret key , email address, telephone number, and your security address. Online data is found the client is web based shopping alluring to use for traps stolen cash in a financial balance, or to perform unlawful exchanges. 

As indicated by experts, dangers for the managing an account and money related exchanges to a limited extent by clients today to share an excessive amount of individual data on informal communities . They are too effortlessly deluded click connections to malevolent sites and stolen individual data, or deceived into giving the username and secret word to the programmer. Likewise with such perspectives, Vo Do Thang said that a gigantic gap is situated in the east office specialists don't have the information of security to get every day email, surfing the web is anything but difficult to tap on the connections produced, stick malevolent and spread quickly over the intranet. Ukraine far reaching power blackouts toward the end of last year in light of staff likewise run open Excel documents sent as email connections containing malignant code. 

The power outage in Ukraine brought about by vindictive code patterns common of network assaults obliterate basic framework, disturb regular day to day existence. On the other hand Hacker assaults utilizing vindictive harm could tangibly harm found in instances of German steel process, before that Stuxnet harmed uranium improvement rotators at Iran's atomic offices. Prior to the present condition of network security improvements progressively mind boggling, security specialists prescribe that with all due respect framework ought to fuse the innovation, procedures and individuals.


Technology with no human face

Awareness risk from cyber increasing and unpredictable, countries, companies, organizations increasingly invest in research, development and application of defense technology. The investment solutions to help early detection of compromised systems is extremely important to take actions to respond quickly, deal promptly potential attacks that traditional methods based defenses sign brand identity is no longer effective virus samples. Modern defense system must be able to detect behavioral attacks, suspicious connections in the system from the outside, abnormal expression of these events ... However, the construction of detection systems early and managed in such events (called SIEM - Security Incident and event management) very expensive.


"The ability to detect hacked improved, but still far from expectations", as identified by VNISA south. The reason is a universal part of the encrypted information with more than 50% of the information is encrypted when transferred over the Internet, it is difficult to monitor in order to detect network attacks.

Security experts said the same about the work of today's defense was not enough to deal with the methods of modern cyber attacks increasingly clever hacker attack tools for continuous improvement, period the survey research objectives. Many reasons were cited as the asynchronous solution, sometimes only focus technology, the process may have been close, but lack of compliance, and the human factor is still weakness in the whole defense system letter.

2016 Status Report of VNISA south ATTT stated, tools, especially the SIEM system is growing and expensive, so the role of monitoring information security engineer has become increasingly important. Knowledge, skill, acumen of monitoring information security professionals is critical to early detection of attacks intentionally. Therefore the training of human resources to information security than ever urgent.

In fact, the survey of the current state of information security south VNISA shows, awareness of information security have changed dramatically in the training, particularly training needs immediately. 50.4% organization training needs immediately on the defensive skills, troubleshooting, analysis of malicious code; followed by the ability to conduct the assessment (audit) and risk management (accounting for 44.1%), and the skills and application protection system (accounting for 43.3%). These figures show that the organization generally recognized weaknesses in human resources in the field of information security. The demand was there, but there are actually deployed suture effective or not is another matter.
