A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Firewalls have been a first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse , modification, or denial of a computer network and network-accessible resources. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions.
Internet security is a branch of computer security specifically related to not only Internet , often involving browser security and the World Wide Web , [ citation needed ] but also network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. Many methods are used to protect the transfer of data, including encryption and from-the-ground-up engineering. The current focus is on prevention as much as on real time protection against well known and new threats. An internet user can be tricked or forced into downloading software that is of malicious intent onto a computer.
Ecommerce sites will always be a hot target for cyberattacks. For would-be thieves, they are treasure troves of personal and financial data. And for businesses of all sizes, the cost of a breach both in loss of data and in customer trust can be hugely damaging for businesses of all sizes. Ecommerce business owners are all too aware of these issues and are increasing their security measures. In this constant game of cat and mouse, as online retailers add increasingly innovative technologies to their sites to stay competitive, cyber attackers are equally honing their skills and finding new vulnerabilities to exploit. The best way to stay ahead is to be aware of ecommerce security best practices and the types of attacks to be on the look out for.

What Is a Firewall?
One of the major challenges that companies face when trying to secure their sensitive data is finding the right tools for the job. Even for a common tool such as a firewall sometimes called a network firewall , many businesses might not have a clear idea of how to find the right firewall or firewalls for their needs, how to configure those firewalls, or why such firewalls might be necessary. A firewall is a type of cybersecurity tool that is used to filter traffic on a network.
What is network security
Almost every medium and large-scale organization has a presence on the Internet and has an organizational network connected to it. Network partitioning at the boundary between the outside Internet and the internal network is essential for network security. It can be a hardware, software, or combined system that prevents unauthorized access to or from internal network. All data packets entering or leaving the internal network pass through the firewall, which examines each packet and blocks those that do not meet the specified security criteria. Deploying firewall at network boundary is like aggregating the security at a single point. It is analogous to locking an apartment at the entrance and not necessarily at each door. Internet is a dangerous place with criminals, users from competing companies, disgruntled ex-employees, spies from unfriendly countries, vandals, etc.
Беккер отбил шестизначный номер. Еще пара секунд, и его соединили с больничным офисом.

Шаги все приближались.
Он хотел говорить, но слова застревали у него в горле. Он протягивал свою изуродованную руку… пытаясь что-то сообщить. Танкадо хотел спасти наш банк данных, - говорила она. - А мы так и не узнаем, как это сделать. - Захватчики у ворот.
- Мне не помешала бы еще одна подушка, если вас это не затруднит. - Нисколько. - Беккер взял подушку с соседней койки и помог Клушару устроиться поудобнее. Старик умиротворенно вздохнул.
- А вдруг Дэвиду грозит опасность. Стратмор покачал головой: - Больше никто не знает о существовании кольца. Именно поэтому я и послал за ним Дэвида. Я хотел, чтобы никто ничего не заподозрил. Любопытным шпикам не придет в голову сесть на хвост преподавателю испанского языка.
