Cybersecurity

Today’s cyber criminals are highly motivated and actively working to understand what types of Cyber Security defenses an organization has deployed. After they know, they then shift to less visible, less detectable patterns of behavior. The unpopular truth is that no protection method is perfect. Inevitably, some threats will be sophisticated and stealthy enough to penetrate all the layers of your defense. These threats can persist within your environment for months or more before being detected. While operating below the radar, the attacks aim to steal critical information, disrupt operations and inflict brand damage.


Cyber Security is not a silver bullet but a complete solution able to:
•    Detect network reconnaissance and network probing that aim to identify attack vectors.
•    Block known and unknown threats that are potentially part of a larger coordinated attack.
•    Detect and block command-and-control (C&C) traffic between the attacker and compromised internal hosts.
•    Track and remediate internal malware propagation aimed at gathering information and disrupting operations.
•    Continuously monitor assets for indications of compromise and shield against zero-day attacks.
•    Be up to date with industry-leading Threat Intelligent sources.


Space Hellas covers all aspects of an effective Cyber Security Architecture.

Cybersecurity

  • Industrial & IoT Security

    The Internet of Things (IoT) is the name applied to all manner of devices from household appliances to aquariums to video cameras that are able to communicate over the Internet. Industrial devices and networks sometimes intertwine with IoT and represent all specialized devices in factories, manufacturing facilities etc., that control mechanical or non-digital functions in general, but are controlled though an IP network. Those devices and networks introduce many security challenges, due to their nature and required functionality. Major concerns are default credentials, no capability for security software installation, vast numbers that can easily go out of control, slow and unwieldy firmware development lifecycles and more. Securing those devices and networks requires specialized solutions and expert architecting.

  • Application Security

    Application security has its foundation on the web application firewall (WAF), an appliance that enforces a set of rules to an HTTP or XML conversation. Generally, these rules cover common attacks such as cross-site scripting (XSS), CSRF and SQL injection. By customizing the rules to the application, many attacks can be identified and blocked. The effort to perform this customization can be significant and needs to be maintained as the application is modified. It controls input, output, and/or access from, to, or by an application or service. It operates by monitoring and potentially blocking the input, output, or service calls that do not meet the configured policy. It can control applications or services specifically, unlike a stateful network firewall, which is - without additional software - unable to control network traffic regarding a specific application.

  • Content Security

    Content Security includes Web and E-mail security. Web Security Gateways offer protection against online security threats by enforcing company security policies and filtering malicious internet traffic in real-time, on premise or in the cloud. A secure web gateway offers URL filtering, application controls for web applications, SSL inspection and the detection, DLP and filtering of malicious code for internal or roaming users. Email Security Relays offer protection against e-mail threats by enforcing company security policies and filtering spam and malicious messages in real-time. An e-mail security relay offers anti-phishing, anti-spam, forged email detection, URL filtering, anti-malware, sandboxing, encryption and DLP.

  • Multifactor Authentication

    Multi-factor authentication (MFA) is an authentication method in which a user is granted access only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something the user and only the user knows), possession (something the user and only the user has), and inherence (something the user and only the user is). These factors can be applied alone or in combination. Single-factor authentication involves the use of exactly one of these three factors to carry out the authentication process being requested. Multifactor authentication helps to ensure that a user is who he or she claims to be via the use of more than one factor to carry out the authentication process being requested. Generally, the more factors used to determine a person’s identity, the greater trust you can place on the authentication. Other factors being equal, you might therefore decide to allow users who have completed multifactor authentication access to more sensitive assets than those authenticated by means of a single factor, such as a password. MFA Solutions can be installed on premise or as a cloud service and include, one-time passwords though SMS or E-mail, USB and time-based tokens and push authentication requests.

  • Network Access Control

    One of the foundational defenses in today’s networks is network access control (NAC). NAC began as a highly structured technology used primarily to help determine network access and establish access control for managed devices. NAC vendors are offering the technology evolved to protect new network architectures. Modern Network Access Control solutions enable the organization to deploy security policies based on the threat and vulnerability attributes received from the threat and vulnerability adapters in addition to network attributes. Threat severity levels and vulnerability assessment results can be used to dynamically control the access level of an endpoint or a user.

  • Network Traffic Analysis

    Network traffic analysis (NTA) uses a combination of machine learning, advanced analytics and rule-based detection to detect suspicious activities on enterprise networks. NTA tools continuously analyze raw traffic and/or flow records (for example, NetFlow) to build models that reflect normal network behavior. When the NTA tools detect abnormal traffic patterns, they raise alerts. In addition to monitoring north/south traffic that crosses the enterprise perimeter, NTA solutions can also monitor east/west communications by analyzing network traffic or flow records that it receives from strategically placed network sensors.

  • Network Security

    Network security is led by the next-generation firewall (NGFW), that is the next generation of network protection, combining a traditional network firewall with other controls, such as an application firewall using deep packet inspection (DPI), an intrusion prevention system (IPS), Anti-Malware engine, file sandboxing, web filtering and/or other technologies such as SSL decryption, QoS, and identity integration (i.e. Active Directory). It can fill the role of an Edge/Internet, Internal/Data Center Firewall or IoT/Industrial Firewall and is the cornerstone of a security architecture. It is complemented by a Security Management Center that provides visibility into network-connected devices combining threat information from security devices and endpoint agents with contextual information about devices including physical and virtual hosts, operating systems, applications, services, protocols, users, geolocation information, content, and network behavior. In addition, it provides access to threat intelligence and the ability to incorporate automation to increase operational efficiency by providing the ability to correlate events and intelligence data to make informed cybersecurity decisions.

  • Endpoint Security (EDR & EPP)

    Endpoint Detection and Response (EDR) is a cybersecurity technology that addresses the need for continuous monitoring and response to advanced threats. It is a subset of endpoint security technology and a critical piece of an optimal security posture. EDR differs from other endpoint protection platforms (EPP) such as antivirus (AV) and anti-malware in that its primary focus isn't to automatically stop threats in pre-execution phase on an endpoint. Rather, EDR is focused on providing the right endpoint visibility with the right insights to help security analysts discover, investigate and respond to very advanced threats and broader attack campaigns stretching across multiple endpoints. Many EDR tools, however, combine EDR and EPP.

  • Cloud Security

    If an organization decides to implement a cloud solution, almost regardless of which model (SaaS, IaaS, or PaaS), the organization must be able to decide whether they can extend their security controls to the cloud solution. Many argue that this approach is impossible, as on-premises controls do not scale to cloud environments. However, general principles such as protection and oversight for access and authentication controls, as an example, are going to remain the customer’s job. A cloud access security broker (CASB) is a security solution or service that sits between an organization's on-premises infrastructure and a cloud provider's infrastructure. A CASB acts as a gatekeeper, allowing the organization to extend the reach of their security policies beyond their own infrastructure.

  • Security Information Event Management (SIEM) & User & Entity Behavioral Analytics (UEBA)

    A security information and event management (SIEM) solution combines security information management (SIM) and security event management (SEM). It provides real-time analysis of security alerts generated by applications and network hardware. User & entity behavior analytics (UEBA) is a cybersecurity process about detection of insider threats, targeted attacks, and financial fraud. UEBA solutions look at patterns of human behavior, and then apply algorithms and statistical analysis to detect meaningful anomalies from those patterns—anomalies that indicate potential threats. All modern SIEM platforms combine both technologies.

  • Unified Endpoint Management

    Mobile devices are prone to many of the same vulnerabilities as other computing systems, but often to a greater degree. For example, desktop systems are far less vulnerable to being stolen. Another example, the wireless network infrastructure, is far less vulnerable to compromise or tampering. As mobile devices are carried around and made accessible to others, they are far more vulnerable outside the organization’s network and physical perimeter. Unified Endpoint Management is a solution that provides a single management interface for mobile, PC and other devices. It is an evolution of, and replacement for, mobile device management (MDM) and enterprise mobility management (EMM) and client management tools. It provides capabilities for managing and securing mobile applications, content, collaboration and more. It is a single approach to managing all endpoints like smartphones, tablets, laptops, printers, ruggedized devices, Internet of Things (IoT) and wearables.

  • Data Loss Prevention

    Data loss prevention software detects potential data breaches/data ex-filtration transmissions and prevents them by monitoring, detecting and blocking sensitive data while in use (endpoint actions), in motion (network traffic), and at rest (data storage). The terms "data loss" and "data leak" are related and are often used interchangeably. Data loss incidents turn into data leak incidents in cases where media containing sensitive information is lost and subsequently acquired by an unauthorized party. Data Loss Prevention (DLP) is a solution that classifies real-time data that is communicated on various channels, by various means. Once classified, the data sent over the communication channel might trigger a policy and generate an incident. Once an incident occurs, an action plan is executed. The action plan may specify which remediation actions to run.
