A. Copy and Paste Naturally, you can copy frames and their content, together or separately, from within InDesign and paste elsewhere within InDesign. You can copy type from the middle of a story and paste it, too. I won’t waste your time talking about something as academic as that. I would like to spend a few paragraphs discussing what can and can’t be copied into InDesign from other applications and some of the things to watch out for when doing that. InDesign’s drawing tools are perfect for most common drawing tasks. When you need something a little more robust, however, haul out Illustrator. When you do that, you have a choice: Save the Illustrator file and place it into InDesign as an asset, or simply copy the artwork from Illustrator and paste into InDesign. Both methods works, and each has its pros and cons. InDesign understands vector paths and basic shapes about as well as Illustrator, and, more importantly, InDesign is wise enough to recognize when something—in this c...

1.1.1 Types Of Detection 1.1.1.1 Signature Detection Protecting the network against known attacks. Attackers often attack networks through tried and tested techniques from previously successful methods. These threats have been analyzed by network security engineers and a listed profile, or specific signature has been created. Signature detection methods examine network by looking for the threat’s fingerprint inside the network traffic and matching against an internal database of known attacks. Once an attack signature is determined, the security device delivers an attack response, mostly in a form of simple alarm or alert. Success in preventing these threats depends on the minute database of attack signatures, compiled from previous records. The drawback to systems on signature detection is clear: they can only detect threats for which there is a defined signature. If signature detection methods are employed to protect networks, the network is protected against known attacks on...

Ten Security Tips 1. Require or encourage workers to choose passwords that are difficult to judge. 2. Workers should change passwords every three months. 3. Make sure your virus protection subscription up to date. 4. Educate workers about the security risks of electronic mail attachments. 5. Implement a comprehensive and complete network security solution. 6. Assess your security regularly. 7. When a worker leaves a company, remove immediately that employee’s network access. 8. If you allow employees to work from home then provide a secure server for remote traffic. 9. Make sure that your Web server software is up to date. 10. It is no recommended that you run unnecessary network services.

1.1 Types of IDS/IPS The following are the types of IDS/IPS 1.1.1 Network Based It performs packet sniffing and evaluates network traffic to recognize and prevent from suspicious activity. They are typically placed inline mode as a network firewall. They receive packets, examine them, decide if they should be permitted, and allow satisfactory packets to pass through. Figure 2- 3 Network based IPS 1.1.2 Host-based It is similar to network-based , apart from that a host-based product senses the characteristics of a single host and the events occurring within that host, similar to sensing network traffic (only for that specific host), system logs, running processes, file access and modification etc.

Classifying Network Security Threats Network security threats can be classified into four broad terms: 1.1.1.1 Unstructured Threats These initiate mostly from non familiar users by using easy existing hacking applications from the Internet. Some of the users in this class are inspired by malicious target but most are encouraged by the academic challenges are known as script kiddies. They are not the most experienced users, or programmers but they have the time and courage. Trojan horse can be explained as software that executes a game on the user’s system. While the user is playing the game, it mails a copy of itself to every client in the user’s contact book. Then other clients get the game and play it, in this case, the Trojan horse spreads.[5] 1.1.1.2 Structured Threats These initiate from users that are motivated and technically competent than script kiddies. They capable of understanding network systems design and the threat of those systems. They have the ability to create ...

Basic Types of Attacks Attack (Single Packet Attack) Atomic Attack (Multi Packet Attack) Types of Network Attacks Attacks Reconnaissance is basically an unauthorized user access to acquire the knowledge of network system devices, applications running on those systems, and the weakness of those systems. This phenomenon is also known as information gathering and, it often precedes a real access or Denial of Service (DoS) attack. 1.1.1.2 Access Attacks Access is a wide terminology that explains to the ability of a certain source to connect to a specific destination. When a destination has been aimed, the intruder will attempt to use some application to trap the victim. This attack can come in the form of unauthorized data recovery or system access. Through this attack hacker can install software on computer which can be used later infect he can perform any action he want. 1.1.1.3 DoS Attacks DoS is an activity when the hacker corrupts the networks, systems, or services in order to ...

Importance of Security The Internet has indeed become the largest data network, enabling and facilitating both personal and industrial communications all over world. The traffic moving over the Internet, as well as commercial networks, is developing exponentially daily. Communication is taking place via electronic mail, mobile users, telecommuters, and regional offices are using the Internet to remotely connect to their business networks, and commercial communication completed over the Internet, via the WWW (World Wide Web). The Internet has changed and greatly expanded according to the need of business, this wide network and its linked technologies have opened the door to an increasing number of security attacks from which companies must guard them. Network attacks are more serious when they are imposed upon businesses that store sensitive data, for example personal financial or medical records, sensitive data can be lost, privacy can be violated, and many hours, or even weeks, of net...
