This document discusses configuring the BIOS security on a computer system. It explains that setting passwords to restrict access to the BIOS and boot manager can help prevent unauthorized users with physical access from booting from removable media or gaining root access. However, the security measures needed depend on how confidential the system's information is and its location. For example, a public display machine without sensitive data may not require such protections, while a laptop left unattended with private SSH keys could lead to a serious security breach if stolen. BIOS security may also be unnecessary if only authorized users have physical access to the system.
Bit locker Drive Encryption: How it Works and How it ComparesLumension
Endpoint security is a rat’s nest of issues, risks and attack vectors. But one thing’s for sure, there is no substitute for encryption - both of local hard drives and removable storage devices. So why are so few of us using encryption at the endpoint?

Eu esperava mais do desempenho e do compromisso do grupo, que poderia ter feito um trabalho brilhante. No entanto, faltou organização e distribuição das tarefas para cada um e não para um só. A equipe fez o relatório e eu tive que concertar muitos erros de ortografia. Foi pedido que o relatório estivesse no trabalho em Power-point, o que a equipe não fez. Também não foram colocadas legendas nas fotos. Tenho certeza de que vocês poderiam ter se empenhado mais e apresentado um trabalho à altura. (Jack) Nota: 1,3

You may be compliant, but are you really secure?Thomas Burg
Presented by Greg Swedosh from Knightcraft Technology (www.knightcraft.com) at NonStop Bootcamp 2014.
This presentation explains why being PCI compliant does *not* equal being secure. While this is a general statement, the presentation does focus on the HP NonStop platform.
Excerpt from a summary slide:
Without a strong commitment to security by the executive team, being compliant only provides a false sense of security.
It often just becomes about ticking boxes and “filling gaps”.
Where there is no serious commitment to security, an organization will always be significantly more vulnerable.
An important issue is how important security is, and how much are we willing to pay it financial, convenience, performance and other terms.

Modern Personal Computer
Boot up Process
The boot up process is necessary for Windows as the hardware does not know where the Operating system is stored. There has to be a simple yet powerful program which loads the kernel in the main memory and executes it. This program in Windows is known as the Bootstrap Loader.
The Windows boot up process comprises of the following procedures:
· The Power-On Self-Test Phase:
Firstly a self-test is performed by the power supply to ensure that the volume and current levels are correct before the Power Good signal is sent to the processor. As soon as this stage is cleared, the microprocessor triggers the BIOS to perform a series of operations.
· BIOS ROM Phase:
BIOS first carry out the P.O.S.T that performs and verifies all initial hardware checks. After this, the hardware' firmware will individually carry out its own diagnostic test such as S.M.A.R.T.
The system will now attempt to determine the sequence of devices to load based on the settings stored in the BIOS to start the operating system. It will start by reading from the first boot up device which usually is the Floppy disk. If the floppy drive does not contain a diskette, it bypasses the first boot up device and detects the second device, which is usually the hard disk. It'll then start by reading the boot code instructions located in the master boot record and copies all execution into the memory when the instructions are validated and no errors are found.
· Boot Loader Phase
Control is then passed on to the partition loader code which accesses the partition table to identify the primary partition, extended partitions and active partition which is needed to determine the file system and locate the operating system loader file which will call upon the boot.ini file which is located at the root directory to determine the location and entries of the operating system boot partition. At this point in time, the boot up menu is displayed on the screen to allow you to select an operating system to start.
NTLDR will pass all information from the Windows registry and Boot.ini file into the next phase.
· Operating System Configuration Phase
Next step is to load the kernel, hardware abstraction layer and registry information.
After this is completed, the control is passed over to the DOS based program which collects and configures all installed hardware devices such as the video adapters and communication ports.
It searches for hardware profiles information and load the essential software drivers to control the hardware devices.
· Security & Logon Phase
Lastly, Ntoskrnl.exe will start up Winlogon.exe which triggers the Lsass.exe or Local Security Administration which is the logon dialog interface that prompts you to select your user profile and verifies your necessary credentials before you are transferred to the Windows desktop.
Scheduling Strategies:
· Windows has 6 process classes with 7 priorities within each class
· Process Classes included:
1. Idle
2. ...
This article will demonstrate how to remotely backup, restore and view data on a tape device using KernSafe iStorage Server. Main reason for using tape device for backup is when you will have for example 3 servers and you would like to backup data from them, before you would need to buy special hardware for each server to perform a backup. That would be very expensive an inconvenient to use. But thanks to the iStorage Server you can use any machine that is able to run a Windows operating system and create a backup on to tape device. Except for that, iStorage Server is also very easy to use.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. CONFIGURACION AUTOMATICA DE SISTEMAS Y
APLICACIONES.
• La configuración es un conjunto de datos que determina el valor de
algunas variables de un programa o de un sistema Operativo, estas opciones
generalmente son cargadas en su inicio y en algunos casos se deberá reiniciar
para poder ver los cambios, ya que el programa no podrá cargarlos mientras
se esté ejecutando, si la configuración aún no ha sido definida por el usuario
(personalizada), el programa o sistema cargará la configuración por defecto
(predeterminada).
3. ADMINISTRAR CUENTAS DE USUARIO.
• La administración de cuentas de usuario y grupos es una parte esencial de la administración de sistemas
dentro de una organización. Pero para hacer esto efectivamente, un buen administrador de sistemas primero
debe entender lo que son las cuentas de usuario y los grupos y como funcionan.
• La razón principal para las cuentas de usuario es verificar la identidad de cada individuo utilizando un
computador. Una razón secundaria (pero aún importante) es la de permitir la utilización personalizada de
recursos y privilegios de acceso.
• Los recursos incluyen archivos, directorios y dispositivos. El control de acceso a estos dispositivos forma una
gran parte de la rutina diaria de un administrador de sistemas; a menudo el acceso a un recurso es controlado
por grupos. Los grupos son construcciones lógicas que se pueden utilizar para enlazar a usuarios para un
propósito común. Por ejemplo, si una organización tiene varios administradores de sistemas, todos ellos se
pueden colocar en un grupo administrador de sistema. Luego se le pueden dar permisos al grupo para acceder
a recursos claves del sistema. De esta forma, los grupos pueden ser una herramienta poderosa para la
administración de recursos y acceso.
4. CONFIGURA EL CIFRADO DE UNIDAD BITLOCKER
*BitLocker es una aplicación de cifrado de disco. La podemos encontrar en versiones de Windows Vista, Windows 7 y Windows
Server 2008 en sus versiones más completas, esta aplicación esta diseñada para proteger los datos e impedir el acceso
no autorizado a cualquier archivo almacenado en la unidad cifrada mediante una clave de 128 bits.
• Para empezar nos dirigimos a Inicio > Panel de control > Sistema y seguridad > Cifrado de unidad BitLocker. En la ventana
que se nos muestra comprobaremos las diferentes unidades de disco duro y extraíbles.
• Clicamos en la opción Activar BitLocker en la unidad a cifrar y el programa comenzara a comprobar la unidad.
• Seguidamente nos mostrara una ventana en la que debemos marcar la casilla “Usar una contraseña para desbloquear la
unidad” e introducir una contraseña a nuestra unidad.
• Después nos dará la opción de Guardar la contraseña en el equipo o imprimirla para recordarla en caso de olvidarla,
seleccionamos la que mejor nos convenga y pulsamos en Siguiente.
5. • Seguidamente debemos confirmar el cifrado de datos, a partir de este punto comenzará a cifrar
los datos de la unidad que hemos seleccionado, y para acceder a ella debemos usar la contraseña que
hemos elegido anteriormente. Clicaremos en Iniciar cifrado.
• No es recomendable retirar nuestra unidad mientras se esta cifrando ya que podríamos dañar
los datos almacenados, recordaros que esto no es definitivo, mas adelante si deseamos quitar el cifrado
podremos hacerlo de la forma que más adelante explicaremos.
• Y ya tendremos nuestra unidad protegida por contraseña, se nos mostrará con un candado.
• Cuando conectemos de nuevo la unidad nos pedirá la contraseña que hemos elegido para
poder acceder a esta.
• Si por el contrario no deseamos que nuestra unidad esté cifrada lo que debemos hacer es lo siguiente:
•
Nos dirigimos a Inicio > Panel de control > Sistema y seguridad > Cifrado de unidad BitLocker y Clicamos
en la opción Desactivar BitLocker, se nos muestra una ventana en la que pulsaremos en Descifrar
unidad.
6. • Y comenzará el descifrado cuando termine solo debemos pulsar en Cerrar.
• Como habéis comprobado con esta aplicación podemos guardar nuestros datos, como un diario o
imágenes para que nadie pueda verlos sin nuestra autorización.
• También es muy útil como medida preventiva en caso de perder nuestro pendrive, de este modo
cualquier persona que lo encuentre no podrá acceder a nuestros datos privados.
• Nota:
•
Siempre que conectemos la unidad a otro equipo debemos introducir la contraseña para
poder acceder a este.
7. CONFIGURAR EL CONTROL PARENTAL.
• Paso 1:
• Dirígete al Panel de Control en el menú de Inicio.
• Paso 2:
• Haz clic en Configurar el Control Parental Para Todos los Usuarios.
• Paso 3:
• Haz clic en cualquier Cuenta Estándar.
• Paso 4:
• Haz clic en Activado para hacer funcionar el Control Parental.
• Paso 5:
• Ahora puedes hacer clic en Límites de Tiempo, Juegos o Permitir y Bloquear Programas Específicos para
configurar el Control Parental.
8. ANTIVIRUS BASADO EN LA NUBE.
• Es un software de protección, que no consume muchos recursos y no necesita de un hardware
considerable para ejecutarse. Además su bases de antivirus nunca se bajarán a tu computadora, si no
que por el contrario, este tipo de antivirus verifica los archivos y los compara con los servidores a los
que se encuentren conectados mediante una conexión a internet.
• Por lo que si se posee conexión a internet, este tipo de software puede detectar más facilmente
cualquier tipo de troyano, spyware, virus, backdoors, etc, con mayor eficacia, ya que su base de datos
está constantemente actualizada.
9. CONFIGURA LA SEGURIDAD EN EL BIOS.
• La protección con contraseñas para el BIOS (o equivalentes al BIOS) y el gestor de arranque, pueden
ayudar a prevenir que usuarios no autorizados que tengan acceso físico a sus sistemas, arranquen
desde medios removibles u obtengan acceso como root a través del modo monousuario. Pero las
medidas de seguridad que uno debería tomar para protegerse contra tales ataques dependen tanto de
la confidencialidad de la información que las estaciones tengan como de la ubicación de la máquina.
• Por ejemplo, si se utiliza una máquina en una exhibición y esta no contiene datos confidenciales,
entonces puede que no sea crítico prevenir tales ataques. Sin embargo, si se deja al descuido en la
misma exhibición, la portátil de uno de los empleados con llaves privadas SSH sin encriptar para la red
corporativa, esto puede conducir a una violación de seguridad importante para la compañía completa.
• Por otro lado, si la estación de trabajo está localizada en un lugar donde sólo los usuarios autorizados o
de confianza tienen acceso, entonces la seguridad del BIOS o del gestor de arranque puede que no sea
necesaria.
