Cyber dangers can originate at any stage of your company. Employers can easily teach Typical social-technical schemes like phishing to their employees. As well as more complex cyber security assaults. Like ransomware and other software meant to scam intellectual assets or private information. Cyber security is critical because it safeguards all data types against stolen and harm—confidential information, sensitive personal details, protected healthcare information, personal information, trade secrets, statistics. And judicial and commercial information systems all fall under this category. Your company won’t protect itself from a cyber attack unless it has a cyber security program in place. Today in our post, we will learn about What is Cyber provides Security? And we will also share some regarded career tips. What do you mean by Cyber Security? Cybersecurity refers to the safeguarding of internet-connected technologies. These technologies include hardware, firmware, and information from cyber threats that individuals and businesses utilize. Mainly to prevent illegal access to information centers and other electronic systems. A solid cybersecurity approach can give a robust defense capability against hostile attacks. These attacks generally target access to, altering, deleting, destroying data. Extorting critical data from a firm’s or individual’s servers also includes. Cybersecurity is also essential in countering hacks that seek to harm or impair the operation of a system or technology. Why do we need Cyber Security? The necessity of cybersecurity is further increasing as our world is more digitally in sync than ever, and this tendency shows no signs of slowing. Data breaches that might lead to identity fraud are increasingly shared openly on social networking sites. Furthermore, social security credentials, credit card...
The President, Nana Addo Dankwa Akufo-Addo, has appointed Dr. Albert Antwi-Boasiako as the Acting Director-General of the Cyber Security Authority (CSA) effective October 1, 2021. Prior to this appointment, he served as the National Cybersecurity Advisor and Head of the National Cyber Security Centre (NCSC), leading Ghana’s institutionalisation of cybersecurity under the policy direction of the Minister for Communications & Digitalisation, Ursula Owusu-Ekuful, who is responsible for cybersecurity matters in government. Dr. Antwi-Boasiako has led the revision of Ghana’s National Cybersecurity Policy & Strategy (NCPS) and the development and passage of Ghana’s Cybersecurity Act, 2020 (Act 1038), two enabling interventions which constitute the anchors of Ghana’s cybersecurity development. In his role as Advisor to the government and the Head of the NCSC, Ghana acceded to the Convention on Cybercrime (Budapest Convention), ratified the African Union Convention on Cyber Security & Personal Data Protection, launched Ghana’s National Cybersecurity Awareness Programme (Safer Digital Ghana), and established Cybercrime and Cybersecurity Incident Reporting Points of Contact which has allowed the public to report cybercrime and cybersecurity incidents. During his tenure as Cybersecurity Advisor, Ghana’s cybersecurity has improved on the ITU’s Global Cybersecurity Index from 32.6% in 2017 to 86.69% in 2021, with Ghana becoming the 3rd most ranked country on the African continent and a global ranking of 43rd from the previous 89th position, a position achieved through his leadership and a collective efforts of the National Cyber Security Technical Working Group (NCSTWG), which was established in 2017 by the then Minister for Communications as part of the institutionalisation of Ghana’s cybersecurity architecture. Dr. Antwi-Boasiako previously served as a Cyber Security Expert with...

My name is Catherine Caldwell, and I am a senior double majoring in French and International and Global Studies with a concentration in peace, security, and human rights in the J. William Fulbright College of Arts and Sciences. Though I have been working on this topic for quite some time, I officially began writing my honor’s senior thesis in fall 2020 with Dr. Laurence Hare, the Director of International Studies, as my mentor. I will defend my thesis and graduate in the spring of 2021 with the intention of attending law school in the fall. My research into the field of cyber security has been in progress since the summer of 2019. I first became interested in the subject during my time at School for International Training in Geneva, Switzerland, when I sat in on a lecture on cyber terrorism and decided to use it as the topic of my capstone project. However, I quickly realized that there was much more to cyber security than I initially realized and decided to establish a foundation of information with the intent to do further research upon my return to the University of Arkansas. Thankfully, I was able to continue my research in Dr. Hare’s Technology and Global Affairs seminar by looking into how multinational corporations have managed to navigate the varied landscape of cyber security within different nations. The thesis topic that I have finally settled on utilizes the knowledge I have gained from these previous two projects and seeks to understand whether positive peace theory is applicable in modern frontier spaces, like cyberspace. Positive Peace is considered to be peace...
Deployment of an Active Directory Certificate Services (AD CS) on a corporate environment could allow system administrators to utilize it for establishing trust between different directory objects. However, it could allow red team operators to conduct an NTLM relay attack towards the web interface of an AD CS in order to compromise the network. The web interface is used for allowing users to obtain a certificate (web enrollment), is over HTTP protocol, doesn’t support signing and accepts NTLM authentication. The details of the attack have been presented by Will Schroeder and Lee Christensen in the Certified Pre-Owned whitepaper. The attack forces the domain controller machine account (DC$) to authenticate towards a host which NTLM relay is configured. The authentication is relayed towards the Certificate Authority (CA) and raises a request for a certificate. Once the certificate is generated for the DC$ account an attacker could use this perform arbitrary operations on the domain controller such as retrieving the hash of the Kerberos account in order to create a golden ticket and establish domain persistence or dump hashes of domain administrators and establish a communication channel with the domain controller. Active Directory Certificate Services can be installed as a role on the domain controller or in an individual server which is part of the domain. The following diagram illustrates the steps of the attack: The attack requires identification of the certification authority. The “certutil” binary is a command line tool which can be used to dump and display certification authority information, verify certificates etc. Therefore it could be used as a quick way to discover if there is a certificate...
We’re inundated with data. Ever-expanding databases and spreadsheets are rife with hidden business insights. How can we analyze data and extract conclusions when there’s so much of it? Graphs (networks, not bar graphs) provide an elegant approach. We often use tables to represent information generically. But graphs use a specialized data structure: Instead of a table row, a node represents an element. An edge connects two nodes to indicate their relationship. This graph data structure enables us to observe data from unique angles, which is why graph data science is used in every field from molecular biology to the social sciences: Left image credit: TITZ, Björn, et al. “The Binary Protein Interactome of Treponema Pallidum …” PLoS One, 3, no. 5 (2008). Right image credit: ALBANESE, Federico, et al. “Predicting Shifting Individuals Using Text Mining and Graph Machine Learning on Twitter.” (August 24, 2020): arXiv:2008.10749 [cs.SI] So how can developers leverage graph data science? Let’s turn to the most-used data science programming language: Python. Getting Started With “Graph Theory” Graphs in Python Python developers have several graph data libraries available to them, such as NetworkX, igraph, SNAP, and graph-tool. Pros and cons aside, they have very similar interfaces for handling and processing Python graph data structures. We’ll use the popular NetworkX library. It’s simple to install and use, and supports the community detection algorithm we’ll be using. Creating a new graph with NetworkX is straightforward: But G isn’t much of a graph yet, being devoid of nodes and edges. How to Add Nodes to a Graph We can add a node to the network by chaining on the return...
