Interview Cyber attack threat Pointing out that the vacancy for quality personnel in cyber security was 59%, Tuna Taktak, Turkey Senior Advisor of Arbor Networks said that the human factor in safety talents had been continuing. The report highlights that the number of companies suffering commitment problems of personnel to service contracts had jumped and the number of attendees from 14% up to 59%. We asked questions to Tuna Taktak about the details of cyber safety. attackers can stay in the network for 200 days without anyone noticing. When attackers are in the internal network, they increase their access and steal the company’s confidential information. These types of attackers create impact by executing patient and informed attacks. Could you give us information about the types of cyber attacks and their definitions? What is the reason for the increase in cyber attacks in the world? Nowadays, there are two important types of cyber attack that are most common. The first is the most common type, DDoS attacks. The purpose of this type of attack is to make websites, applications, and all online services inaccessible. These attacks are constantly evolving, threatening the accessibility of websites and cloud services. These attacks also create a big impact because if a website collapses or is inaccessible, this problem is quickly discovered and news spread. This affects the reputation of the organization, and their opponents can use these disadvantages against them. The other types of attack are advanced attacks. These attacks target any organization, institution or company. As much information as possible about the target is gathered and security systems of the target are examined. The goal is to get inside the company’s internal network and stay there undetected and collect information from within. Researches show that in this type of attack, What are the vulnerabilities of Turkey in the field of cyber security? Cyber security issues in Turkey are the same with everywhere in the world. There are various security levels in the standard security model. This model was effective before cloud computing emerged because companies did not open any information to outside, so the protection policies were well determined and very rigid. But with cloud computing, companies need to share information with other organizations and to make company information accessible via the Internet. For example; they share sales software, CRM information, HR information or they outsource some parts of the company. For this reason, your safety is at most the safety of your weakest point. This provides more points for attackers to exploit. From which countries more attacks come to Turkey? Nowadays, cyber attacks are 42 Eylül <strong>2018</strong>
Interview global. Attacks are made from one source today, and from a different source the next day. With the collaboration between Arbor Networks and Google Ideas we can visualize it. Through Arbor Networks’ ATLAS project, 320 service providers share traffic and attack information. With this information Arbor Networks is able to observe and examine attacks occurring across the world by analysing more than 120Tb traffic at the moment. This is something only Arbor can achieve. Google Ideas took this information and transferred to a visual platform: Digital Attack Map (digitalattackmap.com). This map shows us dynamic, visual, and instant attacks from around the world. What is the basis of cyber defense? Over the past year, many organizations have suffered due to numerous events such as DDoS attacks to systems, services and access, theft of customer information or intellectual/industrial property rights or outage of damaged systems. Today’s problem is that they are exposed to internal and external attacks that target confidential information or business-critical applications. Business continuity or confidential company information are now targeted with threats. Independent of event types, all organizations must be prepared for these types of threats, and there are intervention teams in 60% of organizations. But there are areas where organizations are weaker, such as predicting the effects of attacks on business and detecting attacks within 24 hours. Unfortunately both issues are also very important. Particularly, some regulations require attacks and threats being detected at certain time intervals. How do you define a cyber risk? Nowadays, cyber risk is business risk. These two definitions can be used interchangeably. Successful cyber attacks target customer or company information. The Economist Intelligence Unit’s survey under the sponsorship of Arbor Network shows that there is a growing demand for insurance against cyber attacks. As stated in Arbor’s WISR report, 6% of non-service provider participants have signed contracts with insurance companies to have improvement in this area. Organizations will reinforce their safety stances when the success rates of cyber attacks and the losses resulting from attacks are taken into account. But protecting organizations against today’s threats is not only through technology, it involves people and processes too. Security analysts should analyze, prioritize, and investigate these threats. They should also use necessary threat detection systems and products. What do organizations need to do against cyber threats? Today, firms spend most of their security budgets on the first and last phases of an attack. In the first phase it is to prevent the attack. To protect your networks they use web application firewalls, next-gen firewalls, intrusion prevention systems, antivirus and similar solutions. The last stage is the collection of all the alarms and logs related to the attack, information such as how an attack or threat has intruded. What is missing here is the middle phase. We have to find what the threat has done in the internal network, where did it reach. Organizations have to perceive the threat and intervene more quickly for a better self-protection. What do companies have to do to protect themselves from cyber attacks? Companies should be able to inspect their own networks. They must be aware of communications in their internal networks. They should be able to understand when there is an abnormal or unusual event. When they realize this extraordinary event, they must analyze in detail, see where the attack reaches or try to reach, and obstruct it. How should people and companies prepare against cyber attacks? After all, people constitute all companies. Sophisticated attackers often target employees of companies. They review social media profiles of employees. They prepare a link to an issue that an employee won’t suspect and they install malware on employees’ computers. When an employee clicks this link, the malware will be installed on their computers. When the employee enters the company’s network with their computer, attacker gets what they aim for and reaches the organization’s internal network. These types of attackers are patient and focused on their goal. Effective security is not just about using the necessary security devices. Employees should be trained about safety. Many firms have an event intervention plan, but they don’t have the time to work on these plans or they don’t have enough human resource to implement them. When the attach happens, they can’t fight back strong enough because they didn’t work on these plans thoroughly. Effective security must have all these precautions we mentioned.
